NOTE
: Island and room divider installation is possible as long as
the horizontal portion of the vent system does not exceed 20 feet
with a minimum vertical run of 8 feet (measured from bottom of
appliance).
See details in Venting Section.
NOTE:
When installing this appliance against exterior wall, insulate
to applicable insulation codes.
LOCATING FIREpLACE
When you install your Direct Vent Fireplace in room divider or Flat
on wall corner positions, a minimum of 6 inches clearance must
be maintained from the perpendicular wall to the fireplace opening.
GAS SUppLY
Installing a New Main Gas Cock (Check Local Code)
Each appliance should have its own manual gas cock.
A manual main gas cock should be located in the vicinity of the unit.
Where none exists, or where its size or location is not adequate,
contact your local authorized installer for installation or relocation.
Compounds used on threaded joints of gas piping shall be resistant
to the action of liquefied petroleum gases. The gas lines must be
checked for leaks by the installer. This should be done with a soap
solution watching for bubbles on all exposed connections, and if
unexposed, a pressure test should be made.
Never use an exposed flame to check for leaks. Appliance must
be disconnected from piping at inlet of control valve and pipe
capped or plugged for pressure test. Never pressure test with
appliance connected; control valve will sustain damage!
NOTE:
When using copper or flex connector use, only approved
fittings.
The appliance and its individual shut off valve must be disconnected
from supply piping system during any pressure testing of that system
at test pressures in excess of 1/2 psig (3.5 kPa).
The appliance 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 1/2 psig (3.5 kPa).
CAUTION
If one of the procedures results in pressures in excess of 1/2 psig
(14” w.c.) (3.5 kPa) on the fireplace gas valve, it will result in a
hazardous condition.
Checking Manifold pressures
Both Propane and Natural gas valves have a built-in pressure
regulator in the gas valve. Natural gas models will have a manifold
pressure of approximately 3.5” w.c. (.871 kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 4.5” w.c.
(1.120 kPa) for the purpose of input adjustment to a maximum of
14.0” w.c. (3.484 kPa). Propane gas models will have a manifold
pressure approximately 10.0” w.c. (2.49 kPa) at the valve outlet
with the inlet pressure to the valve from a minimum of 10.8” w.c.
(2.68 kPa) for the purpose of input adjustment to a maximum of
14.0” w.c. (3.484 kPa).
