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 com-
monly known as wellhead gas.
Installation Items Needed
Before installing heater, make sure you have
the items listed below.
•. piping.(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.. See.
Acces-
sories
, page 31.
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 re-
duce incoming gas pressure, heater regulator
damage.could.occur..Install.external.regulator.
with the vent pointing down as shown in Figure
13. Pointing the vent down protects it from
freezing rain or sleet.
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-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.
