Should your appliance be subjected to fire, flood or some other unusual condition, turn off all gas and
electrical power supply. If you are unable to turn off the gas, call your gas company or gas supplier at
once. Do not put the appliance in operation again until it has been ascertained by a qualified agency that
the controls are functioning correctly. The installer should always clearly identify the emergency shut-off
devices and make the owner aware of their location and method of operation.
WARNING
Do not use this appliance if any part has been under water. Immediately call a
qualified service technician to inspect the appliance and to replace any part of
the control system and any gas control which has been under water.
5.2 CHECK FOR GAS LEAKS
To identify gas leaks, smell for gas around the boiler area and gas piping connections. To check a
specific area, including all pipe joints connected to the gas valve, for leakage, spray a mixture of soap
and water onto the suspected area – active bubbling indicates a gas leak. The gas leaks of the joint
connected to the gas valve outlet should be checked when the appliance is on. DO NOT TEST FOR
LEAKS WITH AN OPEN FLAME. Gas leaks must be repaired immediately.
Propane or liquefied petroleum (LP) is heavier than air may collect or "pool" in a low area in the event of a
leak from defective equipment. This gas may then ignite resulting in a fire or explosion. Smell near to the
ground and low points when checking for propane gas leaks.
If you smell gas, STOP! Follow "For your safety read before operating” in
Section 3
.
5.3 CHECK VENTING SYSTEM
A sufficient air supply MUST be provided to this appliance. Check that the air supply inlet and vent
terminations are always kept clear of obstructions and remove any snow, ice, dust, dirt, debris, pests,
etc., which may block proper air flow.
Inspect the entire venting system, including all gaskets, to ensure the system is intact and all joints are
properly sealed. It should be continuous with no separations, leakage, obstructions, discoloration,
depressions or deformation.
5.4 CHECK WATER SYSTEMS
Avoid unnecessary replenishment of water in the CH (central heating) system. It can allow oxygen to
enter the system and cause serious corrosion problems for system components which are not anti-
corrosion type. As well, minerals dissolved in the water supply will precipitate when heated; minerals
preferentially deposit in the heat exchanger. Do not draw water from the central heating system for
cleaning, flushing, etc.
Any audible sounds in the appliance system may be indications of scaling or lack of sufficient water flow
and the system should be checked without delay. Scaling is due to improper maintenance. It is not the
fault of the appliance. Scale damage is not covered by warranty.
Check central heating and domestic hot water systems, including pumps, for leakage.
5.5 CHECK PRESSURE RELIEF VALVES
Pressure relief valves are installed as a code requirement. A pressure relief valve provides extra
protection against damage that could be caused by malfunctioning controls or excessive water pressure.
If a pressure relief valve on each system is not used, the warranty is void.
The pressure relief valves must be installed by a qualified installer in accordance with local codes and
should not be tampered with in any way. The outlet of the pressure relief valve should be positioned over
a suitable drain. The drain pipe must pitch down from the pressure relief valve and should be no smaller
than the outlet of the pressure relief valve. The end of the drain line should not be concealed or threaded
and should be protected from freezing. No valve of any type should be installed between the pressure
