Tundra II Furnace Installation and Operation Manual

9.1.6 Heat exchangers care

Heat exchangers must be cleaned thoroughly at the end of every heating season. During
summer, the air in basements is damper and with minimal air circulation within the furnace,
it can mix with creosote and/or sooth deposits in the exchangers to form an acid that could
accelerate the corrosion process and induce premature decay of the steel. Corrosion
damages are not covered under warranty.
Smoke pipe and exchangers must be inspected regularly during the heating season.
Access to the exchangers is easy and does not require tools;
1. Unscrew the wing nut (B) and remove the washer (C) on the exchanger access door.
