CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 1/2" NPT (National
Pipe Thread) inlet connection to
the pressure regulator.
WARNING: A qualified ser
-
vice person must connect heater
to gas supply. Follow all local
codes.
CAUTION: Never connect
propane/LP heater directly to the
propane/LP supply. This heater
requires an external regulator
(not supplied). Install the exter-
nal regulator between the heater
and propane/LP supply.
WARNING: Never connect
natural gas heater to private
(non-utility) gas wells. This
gas is commonly known as
wellhead gas.
Installation Items Needed
Before installing heater, make sure you have
the items listed below.
• external regulator [propane/LP only] (sup-
plied by installer)
• piping to stove location (check local
codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable al-
ternative to test gauge connection. Purchase
the optional CSA design-certified equipment
shutoff valve from your dealer.
The gas inlet connection for the stove heater
is located on the lower right-hand side of
the stove when viewed from the front of the
unit. The gas connection can be made either
through the bottom right side or through the
lower back opening as illustrated in Figure 6.
Make sure gas log heater is secured to the
stove cavity assembly.
For propane/LP units, the installer must supply
an external regulator. The external regulator
will reduce incoming gas pressure. You must
reduce incoming gas pressure to between 11"
and 14" of water. If you do not reduce incom-
ing gas pressure, heater regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure 7.
Pointing the vent down protects it from freez-
ing rain or sleet.
CAUTION: For propane/LP
units, use only new, black iron
or steel pipe. Internally-tinned
copper tubing may be used in
certain areas. Check your local
codes. Use pipe of 1/2" diameter
or greater to allow proper gas
volume to heater. If pipe is too
small, undue loss of volume
will occur.
