GAS CONNECTION
CHECK GAS TYPE. Use only the gas type indicated on the
heater's rating plate. If the gas type indicated on the plate
is not your type of gas supply, DO NOT INSTALL. Contact
your dealer for the proper model.
GAS PIPING.
The gas supply line must be of an adequate
size to handle the BTU/HR requirements and length of the
run for the unit being installed.
Determine the minimum pipe size from the piping size chart
on page 9. The normal gas connection at this appliance is
1/2" NPT made at the left of the unit.
Always use an an external regulator for all LP installations
to reduce the supply tank pressure to a maximum of 14"
WC. This is in addition to the regulator fitted to the heater.
All piping must comply with local codes and ordinances or with
the National Fuel Gas Code (ANSI Z223.1), whichever applies.
GAS CONNECTION.
If installation is for L.P. gas, have L.
P. installer use two-stage regulation and make all
connections from storage tank to heater. Refer to the
National Fuel Gas Code for the proper supply tank size with
the Btu's/Hr requirements. If this is the ONLY gas
appliance, we recommend a minimum 200 pound cylinder
with a fill gauge. Use of a 100 pound cylinder is not
recommended. Other household gas appliances may
require the tank size to be larger.
Use pipe wrenches when making the connection to the
valve to prevent turning or damage to gas valve.
Connection between the manual shutoff valve and the gas
valve can be made with an CSA design certified flexible
connector if allowed by local codes.
A drip leg (sediment
trap) must be installed, (see figure 5)
. Tighten all joints
securely.
CAUTION: Failure to install a drip leg (sediment trap)
may result in improper combustion that will produce
soot. Reference Sections 3.7 and 5.5.7 and Figure 5.5.7
of the National Fuel Gas Code for guidance.
WARNING
DANGER OF PROPERTY DAMAGE,
BODILY INJURY OR DEATH.
MAKE SURE THE HEATER IS EQUIPPED TO
OPERATE ON THE TYPE OF GAS AVAILABLE.
MODELS DESIGNATED AS NATURAL GAS ARE TO
BE USED WITH NATURAL GAS ONLY. HEATERS
DESIGNATED FOR USE WITH LIQUEFIED
PETROLEUM (L.P.) GAS HAVE ORIFICES SIZED
FOR COMMERCIALLY PURE PROPANE GAS.
THEY CANNOT BE USED WITH BUTANE OR A
MIXTURE OF BUTANE AND PROPANE.
WARNING: Connecting directly to an unregulated
LP tank can cause an explosion.
