INSTALLATION
CONNECTING TO GAS SUPPLY
 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) 
* 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.
Typical Inlet Pipe Diameters
Use 3/8" black iron pipe or greater. Installa-
tion must include an equipment shutoff valve, 
union, and plugged 1/8" NPT tap. Locate NPT 
tap within reach for test gauge hook up. NPT 
tap must be upstream from heater (see Figure 
11, page 15).
IMPORTANT: Install an equipment shutoff 
valve in an accessible location. The equip-
ment shutoff valve is for turning on or shutting 
off the gas to the appliance.
For propane installations, apply pipe joint seal-
ant lightly to male threads. This will prevent 
excess sealant from going into pipe. Excess 
sealant in pipe could result in clogged heater 
valves.
  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: 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" of water. If gas 
line  pressure  is  higher,  heater 
regulator damage could occur.
 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.
