SC Series Boilers – User’s Information Manual

3 AREA AROUND BOILER

Keep boiler area clear and free from combustible materials, gasoline and other flammable vapors and

liquids.

Do not store anything against the boiler or allow dirt or debris to accumulate in the area immediately

surrounding the boiler. It is unsafe for the flow of supply and exhaust air to be obstructed in any way.

Should your boiler be subjected to fire, flood or some other unusual condition, turn off all gas and

electrical supply. If you are unable to turn off the gas, call your gas company or gas supplier at once. Do

not put the boiler 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 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.

4 CHECK FOR GAS LEAKS

To identify gas leaks, smell for gas around boiler area and gas piping connections. To check a specific

area, including the manifold joint connected to the gas valve outlet, for leakage, spray a mixture of soap

and water onto the suspected area – active bubbling indicates a gas leak. DO NOT TEST FOR LEAKS

WITH AN OPEN FLAME.

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 "A" in the safety instructions in Section 2. Gas leaks must be repaired

immediately.

5 CORROSIVE ATMOSPHERES

If a gas boiler is to be installed near a corrosive or potentially corrosive air supply, the boiler should be

isolated from it and outside air should be supplied.

Chemical vapors from products containing chlorine or fluorine must be avoided. Even though these

chemicals may be safe to breathe, corrosive substances can become liberated when passed through a

gas flame. Even at low concentrations, these chemicals can significantly contaminate the air supply and

shorten the life of any gas-fired appliance. The following is a list of some of the products which should be

avoided:

• bleaches and chlorinated cleaning products

• paints and sprays

• water softeners (calcium or sodium chloride)

• leaking refrigeration equipment

• freon from common aerosol dispensers

These chemicals are especially commons near swimming pools, beauty shops, dry cleaning

establishments, laundry areas, workshops, and garages. The warranty is void when failure is due to

corrosion.
