INSTALLATION
CONNECTING TO GAS SUPPLY
CAUTION: For propane gas,
Never connect heater directly
to the gas supply. This heater
requires an external regulator
(not supplied). Install the exter-
nal regulator between the heater
and gas supply. Gas supplier
provides external regulator for
natural gas. The installer pro-
vides the external regulator for
propane gas.
CAUTION: Avoid damage to
regulator. Hold gas regulator
with wrench when connecting
into gas piping and/or ttings.
CAUTION: Use pipe joint
sealant that is resistant to gas
(Propane or Natural Gas).
Before installing heater, make sure you have
the items listed below:
• external regulator for propane unit only
(supplied by installer)
• piping (check local codes)
• sealant (resistant to natural gas and pro-
pane gas)
• equipment shutoff valve*
• test gauge connection*
• sediment trap
• tee joint
• pipe wrench
• exible gas hose (check local codes)
• 3/8" NPT brass tting
* A CSA design-certied equipment shutoff
valve with 1/8" NPT tap is an acceptable al-
ternative to test gauge connection. Purchase
the optional CSA design certied equipment
shutoff valve from your dealer.
WARNING: A qualied ser-
vice technician must connect
heater to gas supply. Follow all
local codes.
WARNING: This appliance re-
quires a 3/8" NPT (National Pipe
Thread) brass inlet connection
to the pressure regulator.
WARNING: For natural gas,
Never connect heater to private
(non-utility) gas wells. This gas is
commonly known as wellhead gas.
WARNING: Do not over-
tighten gas connections.
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
pressure will occur.
CAUTION: For natural gas,
check your gas line pressure
before connecting heater to gas
line. Gas line pressure must be
no greater than 9.5" of water. If
gas line pressure is higher, heater
regulator damage could occur.
