START-UP
PROCEDURES
Lighting the Boiler
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 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
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.
