WARNING

A licensed professional must install the

gas supply.


Turn off 120V power supply.

Turn off the gas.

Gas is flammable. Do not smoke or
provide other ignition sources while
working with gas.

Do not turn on the boiler or gas until all
fumes are gone.
IMPORTANT

The boiler shall be installed such that
the gas ignition system components
are protected from water (dripping,
spraying, rain, etc.) during appliance
operation and service (circulator re-
placement, condensate trap, control
replacement, etc.).

A sediment trap must be provided
upstream of the gas controls.

A manual gas shutoff valve between
the gas supply and the boiler must be
installed.

1. Check the type of gas and gas supply
pressure before connecting the boiler. If the
boiler is not of the gas type that the building
is supplied with, converting the gas type of
the boiler is necessary. A gas conversion kit is
included with the boiler. Refer to section
"14.5 Gas Conversion" in the Appendix for
gas conversion instructions.
2. Check the gas supply pressure immediately
upstream at a location provided by the gas
company. Supplied gas pressure must be
within the limits shown in section "3.4
Specifications" with all gas appliances
operating.
3. Before placing the appliance in operation, all
joints including the heater must be checked
for gas tightness by means of soap, gas leak
detector solution, or an equivalent
nonflammable solution, as applicable. Since
some leak test solutions, including soap and
water, may cause corrosion or stress
cracking, the piping shall be rinsed with
water after testing, unless it has been
determined that the leak test solution is non-
corrosive.
4. Use approved and appropriately sized
connectors to connect the boiler to the gas
line. Purge the gas line of any debris before
connection to the boiler.
5. Any compound used on the threaded joint of
the gas piping shall be a type that resists the
action of liquefied petroleum gas (propane/
LPG).
6. The gas supply line shall be gas tight, sized,
and so installed as to provide a supply of gas
sufficient to meet the maximum demand of
the heater and all other gas consuming
appliances at the location without loss of
pressure. If in doubt about the size of the gas
line, refer to section "6.3 Gas Pipe Sizing
Reference Tables."
7. Perform a leak and pressure test prior to
operating the boiler. If a leak is detected, do
not operate the boiler until the leak is
repaired.
