Building value in Air.
Hello - I’m Mike Carter - an application engineering specialist for Greenheck.
Today, we will be covering the installation procedure of the Fire Ready Range Hood.
Before beginning work on any equipment, it is important to adhere to safety standards.
Be sure to wear the appropriate Personal Protection Equipment.
The product will arrive in a large carton on a pallet.
First, thoroughly check to ensure all items are accounted for – there may be several
boxes strapped to the product depending on what types of accessories were ordered.
Bulky accessories such as ceiling enclosures may ship loose in separate boxes.
Anything missing or damaged should be noted on the bill of lading.
It is highly recommended to have a copy of the installation and operations manual (IOM)
on hand before arriving on site.
The IOM contains important information regarding the installation, maintenance and troubleshooting
if needed.
It also has copies of wiring diagrams that will help in the process of wiring the hood.
A copy of this document is ships in the product packaging, and is also available at Greenheck
dot com.
Typically, the job of installing the hood is the responsibility of the mechanical contractor
but coordination between different trades is very important.
One of the first things prior to hanging the hood is to determine the number of electrical
circuits needed from the breaker panel to the hood.
It is recommended that before drywall is hung, all electrical cables be run through the wall
to their corresponding components.
Determine the hood mounting height, using guidelines of maximum spacing of 30 inches
to a minimum of 24 inches from the bottom of the hood to the range top.
Locate the hood mounting plate in the packaging and consult the IOM for dimensional data and
details on installing the bracket.
Attach the bracket to the wall in the desired location and securely fasten with the proper
field provided fasteners.
Ensure the distance from the bottom of the bracket to the cooking surface is between
24 and 30 inches.
Make sure the bracket is safely secured to wall studs to prevent potential damage to
the product or serious injury.
The hood can weigh up to 93 pounds.
If the hood was purchased with the available external inline fan option, it will need to
be installed vertically or horizontally in the ductwork running between the unit and
roof or wall cap.
Check that the fan is installed with the airflow arrow on the side of the fan directed away
from the hood and in accordance with the information seen in the IOM.
Attach the ductwork to the 8-inch collar adapter on the hood mounting bracket.
Remove the hood from the crating and remove the grease filter.
Carefully lift the hood into place onto the lower hood tabs on the wall mounting bracket
with a helper.
While supporting the hood, hook the safety cable to the chain link on the mounting bracket,
and screw the nut to close the link.
The hood is now in the service position.
Locate the range disconnect assembly and gas valve if applicable.
Range disconnects are offered in either gas or electric configurations.
There are two different types of range disconnect options.
First is a gas-range disconnect which utilizes an external gas valve and also includes an
electric disconnect, since many gas ranges have an electric power connection.
The second disconnect option is used for an electric-only range.
The disconnect should be mounted behind the range or in cabinet next to range.
Dimensions for these components are shown in the IOM.
Note the plug and play electrical cables for the disconnect are 10 feet long, so make sure
to mount the disconnect close enough so that the cables will reach.
We will cover wiring in more detail later.
The hood seen here is configured with cabinets above it, but the Fire Ready Range Hood is
also available with several other accessories, such as ceiling enclosures or a finished top.
Dimensional data and further installation details can be found in the IOM for these
items.
The Fire Ready Range Hood features a plug and play design for simplicity and ease of
installation.
Cables are supplied with connectors on the ends, so it is important to size conduits
adequately to allow the connectors to pass through unobstructed.
A few connections will require wiring to be supplied in the field.
You will need to run 115 volts AC from a 15-amp non-shunted breaker through a one inch knockout
in the control j-box behind the hood mounting bracket, then into the hood.
Terminate the hot on terminal H1, neutral on terminal N1, and ground on the green GND
terminal.
Make sure there is enough slack in the wiring to prevent tension on the wires when the hood
is lowered into its service position.
If the hood was provided with an internal fan, the fan is wired from the factory
If provided with an external inline fan, the hood will be provided with a 50-foot, 4-wire
plug and play cable with an orange label.
Connect this cable to the orange plug and play harness at the fan, run it down to the
hood and through a two-inch knockout in the controls j-box.
Connect the orange plug and play harness in the hood
For a fan by others, there will also be a 50-foot 4-wire plug and play cable the same
as discussed previously.
Connect the harness to the orange plug existing in the hood and then connect the 1-foot fan
harness extension to the fan side as shown here.
For a gas range disconnect, if the gas range has a 115-volt ac cord, plug this cord in
here to the receptacle labeled “RANGE”.
Then plug the gas valve one-and-a-half-foot whip into the 5-foot gas valve cord coming
off the bottom of the gas disconnect assembly.
Plug in the gas disconnect 5-foot power cord to a 115-volt receptacle near the range.
Next there will be two plug and play 10-foot cables coiled up in the hood
Run these through a 2-inch knockout in the control j-box down to the gas shut off assembly.
Connecting them here on the disconnect
For the electric range disconnect assembly, start by plugging the disconnect two-and-a-half
foot.
Four-prong power cord into a 250-volt AC receptacle near the range.
Then connect the range power cord into the 250-volt AC receptacle on the disconnect
Lastly you will connect the two, 10-foot plug and play cables similar to as we described
earlier with the gas disconnect.
Simply find the cables coiled up in the hood and run them down to the disconnect to plug
in here.
Now we’ll run through some of the connections for a few of the options and accessories.
For more details on other accessories not covered in this video, please consult the
IOM.
A Manual pull station can be supplied for fire suppression system activation.
To connect this accessory, plug the 30-foot plug and play cable into the “REMOTE PULL”
plug housing on the fire suppression control board here.
If supply fan interlock control capability is desired, this can be accomplished by using
the supply fan interlock contacts tied to terminals R and G inside the hood seen here.
The terminals are dry with no voltage and connected to a normally open contact that
closes when the supply fan should run.
These connections can be used to drive a device that controls a supply fan if make up air
is necessary.
Fire system contact connections are available on terminals C6, NC6 and NO6
C6 and NO6 terminal blocks are a dry, normally open contact that closes in the event of a
fire.
C6 and NC6 are a dry, normally closed contact that opens in the event of a fire.
These contacts can be used to activate fire alarms, shunt trip breakers or other accessories
as required in the field
You have now successfully completed an installation of a Greenheck Fire Ready Residential Range
Hood.
