HeatPack Furnace Installation and Operation Manual

 Maximum unsupported horizontal length: 3 feet (1 m);

 Galvanized flue pipes must not be used because the coating vaporize at high

temperatures and release dangerous gases;

 Flue pipes must be at least 24 gauge in thickness;

 The chimney connector must be in good condition;

 Flue pipe joints should overlap 1 1/4". (30 mm);

 It should not be necessary to move the furnace to maintain the exhaust system.

 The male ends of the pipe sections must be oriented towards the appliance so that

falling dust and condensation stay inside the pipe;

 The use of 45° elbows is strongly recommended;

 Never use more than two 90° elbows.

Use 45° elbows where possible, rather than 90° elbows.

Alternative installations with 90° elbow or tee.
