WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct, and strict
adherence to applicable jurisdictional/
professional codes and regulations.
Do not use matches, candles, fl ame or
other sources of ignition to check for gas
leaks.
DO NOT USE GASOLINE, CRANKCASE OIL
OR ANY OIL CONTAINING GASOLINE. If in
doubt, contact your Fulton representative
prior to operation.

CAUTION
Some soap used for leak testing is corrosive
to certain types of metals. Clean all piping
thoroughly after completing the leak check.
Eliminate System Air
NOTE: There are no built-in boiler air eliminating features.
Adhere to the following for air elimination:
1. The installation of an air separator and air eliminator (air vent) is required.
2. To prevent scale corrosion in boiler and associated piping, make up water
must be kept to a minimum. This is best achieved by ensuring immediate
repair of all leaks and that system pressure is maintained.
3. If a sealed diaphragm-type expansion tank is used, install an air eliminator
in the hot water piping at the air separator.
4. If an air cushion type expansion tank is used, pipe tank directly into boiler
supply.
5. On multi-zoned systems (or a system with both space and domestic water
heating), air elimination must be provided either in the common piping or
on every loop.
6. When the boiler is installed at a higher level than baseboard radiation (if
used), air elimination must be provided directly above the unit.
Fill the Boiler With Water
To be sure that the boiler is not air-bound, open the pressure-relief valve located
at the rear of the boiler. Leave the relief valve open until a steady fl ow of water is
observed. Close the valve and fi nish fi lling the system.
Install Gas Piping
The Reliance boiler is factory test fi red and combustion is adjusted per the boiler
data plate and test fi re sheet.
The gas train (Figure 7) components are UL-795 certifi ed to operate at specifi c
gas pressure requirements. If available gas pressure is greater than 14” W.C., a
lock up style gas pressure regulator must be provided to reduce the provided
pressure to the acceptable range of 3.5” W.C. to 14” W.C. for natural gas, and 7”
W.C to 14” W.C. for propane.
Adhere to the following for gas piping installation:
1. See Table 3 for required natural gas pipe size, based on overall length of
pipe from the meter plus equivalent length of all fi ttings. Approximate
sizing may be based on 1,020 BTU for 1 cubic foot of natural gas.
2. Piping must be installed such that no piping stresses are transmitted to the
boiler. The boiler cannot be used as a pipe anchor.
3. The boiler and all gas piping connections must be pressure-tested and
checked for leaks before being placed into service. Test with compressed
air or inert gas if possible.
