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 the latest edition of the ANSI-Z21.13/CSA 4.9
Standard.
For Standing Pilot Models
A. This boiler has a pilot which must be lighted by
hand. When lighting the pilot, follow these instruc-
tions 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 set-
tle 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 neigh-
bor'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 techni-
cian 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
Flush system before putting into operation to ensure
that foreign material does not damage pump seals. 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 sys-
tem 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 separate-
ly. Isolate the other zones while one zone is being
purged of air.
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.
CAUTION: Propane gas is heavier than air and
sinks to the ground. Exercise extreme care in lighting
boiler in confined areas.
WARNING: If you do not follow these instructions
exactly, a fire or explosion may result causing
property damage, personal injury or loss of life.
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.
NOTE: Circulator motor supplied with the boiler
does not require lubrication.
