Troubleshooting Coal, Wood, and Multi-Fuel Furnaces
The troubleshooting sections that follow list the most common problems associated with coal, wood, and multi-fuel furnaces. Each problem is given in the form of a symptom, the possible cause or causes, and some suggested remedies (Tables 13-4, 13-5, and 13-6).
Caution
Gas odors around a multi-fuel (gas/coal or gas/wood) furnace may indicate a safety problem. If you smell gas,
(1) immediately open some windows;
(2) extinguish any open flame;
(3) do not touch any electrical switches; and
(4) immediately call the local gas company for advice.
