LOCATION
•
DO NOT
install this furnace in a mobile home. This furnace
is designed only for installation in buildings constructed
on site and connected to ductwork. When installed in a
utility room or closet, the door should be wide enough to
allow the largest part of the furnace to enter, or to permit
the replacement of another appliance, such as a water
heater. This furnace is designed to be installed indoors
only.
•
DO NOT
install outdoors. This furnace should be installed
in such a manner so that it is protected from water. If any
components should become wetted or submerged under
water, replace those parts before returning the furnace to
operation.
•
DO NOT
use as a construction heater.
•
DO NOT
use in an area where freezing may occur without
properly protecting the vent and drain system. The drain
may crack and leak if subjected to freezing temperatures.
•
DO NOT
install in a room used or designed to be used as
a bedroom, bathroom or storage closet, or in any enclosed
space with access only through such a room or space.
A return air filter grille or means of inserting a filter into the
return air duct is recommended. The opening in the duct
used for filter access must be capable of being sealed air
tight if located in the same pressure zone as the furnace.
The furnace and it’s individual shut-off must be disconnected
from the gas supply piping system during any pressure
testing of that system at test pressures in excess of 1/2
psig (3.5kPa)
The furnace must be isolated from the gas supply piping
system by closing it’s individual manual shut-off valve during
any pressure testing of the gas supply piping system at
pressures equal to or less than 1/2 psig (3.5 kPa).
CLEARANCES
MIN. CLEARANCES TO COMBUSTIBLE SURFACES
Unobstructed front clearance of 24" for servicing is
recommended.
RIGHT SIDE
- 1"
VENT
- 0"
REAR
- 0"
LEFT SIDE
- 1"
TOP OF PLENUM
- 1"
FRONT
- 3"
Line contact is permitted in the horizontal position.
ACCESSIBILITY CLEARANCE, WHERE GREATER,
SHOULD TAKE PRECEDENCE OVER MINIMUM FIRE
PROTECTION CLEARANCE.
A gas-fired furnace for installation in a residential garage
must be installed so that the ignition source and burners
are located not less than eighteen inches (18") above the
floor and is protected or located to prevent physical damage
by vehicles.
A gas furnace must not be installed directly on carpeting,
tile, or other combustible materials other than wood flooring.
WARNING
COMBUSTIBLE MATERIAL MUST NOT BE PLACED ON OR
AGAINST THE FURNACE CABINET. THE AREA AROUND
THE FURNACE MUST BE KEPT CLEAR AND FREE OF ALL
COMBUSTIBLE MATERIAL INCLUDING GASOLINE AND
OTHER FLAMMABLE VAPORS AND LIQUIDS. THE USER
MUST BE CAUTIONED THAT THE FURNACE AREA MUST
NOT BE USED AS A BROOM CLOSET OR FOR ANY OTHER
STORAGE PURPOSE.
WARNING
A SOLID METAL BASEPLATE IS SUPPLIED WITH THIS
FURNACE. THIS BASEPLATE MUST BE IN PLACE AND
SEALED AIR TIGHT WHEN THE FURNACE IS INSTALLED
WITH SIDE RETURN AIR DUCTS. FAILURE TO DO SO
MAY PERMIT COMBUSTION PRODUCTS, INCLUDING
CABON MONOXIDE, TO ENTER THE LIVING SPACE AND
CREATE POTENTIALLY HAZARDOUS CONDITIONS SUCH
AS
CARBON MONOXIDE
POISONING OR DEATH. FULL
SIZE RETURN AIR DUCT OPENINGS MUST BE UTILIZED.
EMBOSSES ARE PROVIDED FOR THIS PURPOSE.
Before proceeding with this installation check the following:
• Correct clearance from combustible materials
• Adequate accessibility for servicing
• Flooring is not carpet or any other combustible material,
except wood
• Adequate combustion / ventilation air is supplied
• Metal base plate is in place when using side(s) for return
air
• In a garage, the furnace has been adequately elevated
and protected from vehicle damage
• Furnace area is free of flammable materials and vapors
such as gasoline
COMBUSTION AIR
The GMNT furnace can be installed either as a Direct Vent
(2 pipe) or a Non-Direct Vent (1 pipe) appliance. If installed
as direct vent appliance, the combustion air is to be taken
from the outdoors via a 2" or 3" schedule 40 PVC pipe and
terminate at the furnace burner box. As a non-direct vent
furnace, the combustion air is taken from the area which
the furnace is installed. Avoid combustion air sources that
contain flammable fumes and vapors, and gasses such as
carbon monoxide, hydrogen sulfide, ammonia, chlorine, and
halogenated hydrocarbons.
Direct Vent Combustion Air.
As shown in the following
illustration, the combustion air pipe is to originate at the
furnace’s cabinet and terminate outside of the building. The
diameter of the PVC combustion air pipe depends upon
the furnace size, the length of pipe, and the quantity of
fittings employed. The table found in the “Combustion/Vent
Pipe Size” section of this manual outlines these sizing
requirements. As a direct vent installation, the “Air for
Combustion and Ventilation Air” requirements found in ANSI
Z223.1, section 5.3 is not required for the furnace to operate
correctly. However, other fuel burning appliances located
in the same space as the furnace may still require that the
area be serviced with Combustion and Ventilation Air
consistent with ANSI Z223.1, section 5.3.
