GOLD CGi Gas-Fired Water Boiler — Boiler Manual

7a Start-up — preparation

Check for gas leaks

Before starting the boiler, and dur- ing initial operation, smell near the floor and around the boiler for gas odorant or any unusual odor. Do not proceed with start-up if there is any indication of a gas leak. Repair any leak at once.

Propane boilers only — Your pro-

pane supplier mixes an odorant with the propane to make its presence detectable. In some instances, the odorant can fade and the gas may no longer have an odor.

•Propane gas can accumulate at floor level. Smell near the floor for the gas odorant or any unusual odor. If you suspect a leak, do not attempt to light the pilot.

•Use caution when attempting to light the propane pilot. This should be done by a qualified service technician, particularly if pilot outages are common.

•Periodically check the odorant level of your gas.

•Inspect boiler and system at least yearly to make sure all gas piping is leak-tight.

•Consult your propane supplier regarding installation of a gas leak detector. There are some products on the market intended for this purpose. Your supplier may be able to suggest an appro- priate device.

Determine if water treatment is needed

Do not use petroleum-based cleaning or sealing

compounds in boiler system. Severe damage to boiler will occur, resulting in substantial property damage.

Eliminate all system leaks. Continual fresh makeup water will reduce boiler life. Minerals can build up in sections, reducing heat transfer, overheating cast iron, and causing section failure.

Verify water chemistry

Consult local water treatment companies for unusually hard water areas (above 7 grains hardness) or low pH water conditions (below 7.0). Boiler water pH of 7.0 to 8.5 is recommended.

Freeze protection (when used)

Use antifreeze made especially for hydronic systems. Inhibited propylene glycol is recommended.

Do not use ethylene glycol, automotive or undiluted antifreeze. Severe personal injury or death can result.

1.Determine antifreeze quantity according to system water content. Boiler water content is listed on page 67. Remember to include expan- sion tank water content.

2.Follow antifreeze manufacturer’s instructions.

3.A 50% solution of propylene glycol/water provides maximum protec- tion to about -30°F.

4.Local codes may require back flow preventer or actual disconnect from city water supply.

5.When using antifreeze in a system with automatic fill, install a water meter to monitor water makeup. Glycol will leak before the water begins to leak, causing glycol level to drop. Added water will dilute the antifreeze, reducing the freeze protection level.
