Outdoor Installation

If installing outdoors in a location that may experience
freezing temperatures, precautions must be taken to
prevent water in the heat exchanger and condensate
inside and outside of the boiler from freezing. Damage
due to freezing water or condensate is not covered by
the warranty.
For proper operation in outdoor installations,
the boiler must be equipped with the inlet air and
exhaust terminal kits listed in Table 10. Additional
instructions are supplied with the terminal kits.

GAS SUPPLY AND PIPING

4.0 Gas Supply and Piping
All Installations must conform to the National Fuel
Gas Code ANSI Z223.1/NFPA54, and/or local codes.
In Canada, the installation must conform to the latest
edition of CSA B149.1 Natural Gas and Propane
Gas Installation Code, and/or local codes. Gas
piping should be supported by suitable hangers or
Review the following instructions before proceeding with the
installation.
by checking the rating plate. Units are normally equipped
to operate at elevations up to 2000 feet (610m).
However, the appliance will function properly without
10,000 feet (3050 m).
2. The gas pressure settings must match fuel type as
shown in Table 11
3. Table 12 and Table 13 on page 19 offer some gas pipe
sizing information. Refer to the applicable gas code for
more detailed sizing information.
4. Run gas supply line in accordance with all applicable
codes.
5. Locate and install manual shutoff valves in accordance
with state and local requirements.
6. A sediment trap must be provided upstream of the gas
controls.
7. All threaded joints should be coated with piping
8. The appliance and its individual shutoff valve must be
disconnected from the gas supply piping during any
pressure testing of that system at test pressures in
excess of 1/2 PSIG (3.45kpa).

could result in property damage, serious
injury or death.
Note - The unit and all other gas appliances
maximum capacity to properly measure the inlet
supply pressure. The pressure can be measured
at the supply pressure port on the gas valve.
Low gas pressure could be an indication of an
undersized gas meter, undersized gas supply
lines and/or an obstructed gas supply line.
The units may be equipped with low and high
pressure gas switches that are integrally vent
limited. These types of devices do not require
venting to atmosphere.
9. The unit must be isolated from the gas supply
system by closing its individual manual shutoff
valve during any pressure testing of the gas
supply piping system at test pressures equal to or
less than 1/2 PSIG (3.45kpa).
10. The appliance and its gas connection must be
leak tested before placing it in operation.
11. Purge all air from gas lines
