Locations; Installation - COZY DVCF402D Owner's Manual

1. This furnace must be installed on an outside wall and vented to the
outside. If possible, this wall should be on the side of the house that
receives the least amount of wind since strong gusting winds could
cause pilot outage.
2. For most efficient performance, locate furnace as centrally as
possible in the area to be heated.
3. The furnace can be installed flush against a wall or recessed up to
10" maximum. For proper combustion, make sure unit is level front
to back and side-to-side.
4. Do not install the furnace in a closet, alcove or small hallway where
the furnace could be isolated from the space to be heated by closing
a door.
5. Be sure the vent cap will have the proper clearances.
(See Figure 2a)
6. Check inside the wall to make sure there are no obstacles such
as water pipes, electric wiring, etc. which could interfere with the
installation of the furnace or vent tubes.
7. Be sure to maintain adequate accessibility clearances for servicing
and proper operation.
8. If the furnace is installed in a basement, a 12" clearance must be
maintained between ground level and the bottom of the vent cap. Do
not install furnace where vent cap will terminate in a window well or
any other opening below ground level.
ELECTRICAL ROUGH-IN
For convenience, this furnace is equipped with a three-prong power cord
located on the top left of heater. The 115V wiring should be brought in
on the left side terminating in a receptacle box (not provided). Consult
local codes or ordinances. (For Amps, see Page 3 / Specifications and
Dimensions).
ROUGH-IN GAS SUPPLY
Install a 1/2 inch diameter gas supply line. The gas line can enter the
cabinet through the right side or bottom (See Figure 3). The gas line
must have an individual manual shut off valve. Also, you must install a
drip leg and provide a 1/8" N.P.T. plugged tapping, accessible for test
gauge connection, immediately upstream of the gas supply connection
to the furnace (See Figure 4).
The furnace and its individual shut off valve must be disconnected from
the gas supply piping system during any pressure testing of that system
at test pressures in excess of ½ psig (3.5kPa). The furnace must be
isolated from the gas supply piping system by closing its individual
manual shut off valve during any pressure testing of the gas supply
piping system at test pressures equal to or less than ½ psig (3.5kPa).
