PROPANE BOILERS ONLY
– Propane suppliers mix an odorant with the gas to make its presence detectable. In some instances, the
odorant can fade, and the gas may no longer have an odor. Before startup and periodically thereafter, have the propane supplier verify
the correct odorant level in the gas.
FOR YOUR OWN SAFETY READ BEFORE OPERATING
1. This boiler does not have pilot. It is equipped with an ignition device which automatically lights the burner. Do not try to light the
burner by hand.
2. BEFORE OPERATING: 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 boiler.
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 suppliers' instructions.
If you cannot reach your gas supplier, call the fire department.
Turn off gas shutoff valve (located outside of the boiler) so that the handle is crosswise to the gas pipe. If the handle will not
turn by hand, don't try to force or repair it, call a qualified service technician. Force or attempted repair may result in a fire or
explosion.
4. 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 that has been damaged.
5. The boiler shall be installed so the gas ignition system components are protected from water (dripping, spraying, rain, etc.) during
boiler operation and service (circulator replacement, condensate trap, control replacement, etc.)
Failure to follow these instructions could result in property damage, serious personal injury, or death.
If you discover any evidence of a gas leak, shut down the boiler at once. Find the leak source with a bubble test and repair immediately.
Do not start the boiler again until the leak is repaired. Failure to comply could result in substantial property damage, severe personal
injury, or death.
D. FILL AND TEST WATER SYSTEM
Ensure the boiler is full of water before firing the burner. Failure to do so will damage the boiler. Such damage IS NOT covered by
warranty, and could result in property damage, severe personal injury, or death.
1. Fill the system only after ensuring water chemistry meets the requirements listed in this manual.
2. Close the manual and automatic air vents and boiler drain valve.
3. Fill to the correct system pressure. Correct pressure will vary with each application.
a. Typical cold water fill pressure for a CH residential system is 12 psi.
b. Pressure will rise when boiler is turned on and system water temperature increases. Operating pressure of the CH system
should never exceed 25 psi, and must never exceed the relief valve pressure setting.
4. At initial fill and during boiler startup and testing, check system thoroughly for leaks. Repair all leaks before proceeding further.
Eliminate all system leaks. Continual fresh make-up water will reduce boiler life. Minerals can build up in the heat exchanger, reducing
heat transfer, overheating the heat exchanger, causing heat exchanger failure and possibly resulting in property damage, severe
personal injury, or death.
5. The system may have residual substances that could affect water chemistry. After the system has been filled and leak tested, verify
that water pH and chlorine concentrations are acceptable by sample testing.
