START-UP PROCEDURES
Lighting the Boiler
Safe-lighting and other performance criteria were met
with the gas manifold and control assembly provided on
the boiler when the boiler underwent tests specified in
ANSI-Z21.13a 1983 Standard.
CAUTION: Propane gas is heavier than air and sinks to
the ground. Exercise extreme care in lighting boiler in
confined areas.
For Standing Pilot Models
WARNING: If you do not follow these instructions
exactly, a fire or explosion may result causing property
damage, personal injury or loss of life.
A. This boiler has a pilot which must be lighted by
hand. When lighting the pilot, follow these instructions
exactly.
B. BEFORE LIGHTING Smell all around the boiler
area for gas. Be sure to smell next to the floor because
some gas is heavier than air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
• Do not try to light any appliance.
• Do not touch any electric switch;
• Do not use any phone in your building.
• Immediately call your gas supplier from a
neighbor's phone. Follow the gas supplier's
instructions.
• If you cannot reach your gas supplier, call the
fire department.
C. Use only your hand to push in, move or turn the gas
control knob or lever. Never use tools. If the knob or
lever will not push in, move or turn by hand, don't try to
repair it, call a qualified service technician. Force or
attempted repair may result in a fire or explosion.
D. Do not use this boiler if any part has been under water.
Immediately call a qualified service technician to inspect
the boiler and to replace any part of the control system
and any gas control which has been under water.
Filling the System
Fill system with water. Purge all air from the system
using purge valve sequence. After system is purged of
air, lower system pressure. Open valves for normal
system operation, fill system through feed pressure
regulator to minimum 12 PSI. Manually open air vent
on the compression tank until water appears, then close
vent.
On multiple-zone systems, purge each zone sepa-
rately. Isolate the other zones while one zone is being
purged of air.
Flush system before putting into operation to ensure
that foreign material does not damage pump seals.
Checking the Circulator
Before lighting the boiler and after system is filled,
make sure that circulator is operating properly. Manual
gas valve should be off. By adjusting the wall thermo-
stat to the maximum setting, circulator should run
immediately and allow water to flow through the boiler
and the entire system.
NOTE: Circulator motor supplied with the boiler does
not require lubrication.
CAUTION: In case of a prolonged power failure during
freezing weather conditions, boiler and piping system
must be drained completely to avoid possible damage
to the heating system.
