INSTALLATION
CONNECTING TO GAS SUPPLY
  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" WC. If gas 
line pressure is higher, heater 
regulator damage could occur.
 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/LP or Natural Gas).
Before installing heater, make sure you have 
the items listed below:
•  external regulator for propane/LP unit only 
(supplied by installer)
•  piping (check local codes)
•  sealant (resistant to natural gas and pro-
pane/LP gas)
•  equipment shutoff valve*
•  test gauge connection*
•  sediment trap
•  tee joint 
•  pipe wrench
•  exible gas hose (check local codes) 
* 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 
requires a  3/8" NPT  (National 
Pipe Thread) inlet connection to 
the pressure regulator.
 WARNING: Do not over-
tighten gas connections.
 WARNING: For natural gas, 
Never connect heater to private 
(non-utility) gas wells. This gas is 
commonly known as wellhead gas.
 CAUTION: For propane/LP gas, 
never connect heater directly to the 
gas supply. This heater requires 
an external regulator  (not  sup-
plied). Install the external regulator 
between the heater and propane/
LP supply. Gas supplier provides 
external regulator for natural gas. 
The installer provides the external 
regulator for propane/LP gas.
 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.
