temperatures and release dangerous gases;
o
Flue pipes must be at least 24 gauge in thickness;
o
The chimney connector must be in good condition;
o
Flue pipe joints should overlap 1 1/4". (30 mm);

Straight up installations needs to have either a connector where one end has no
fastener or a telescopic length;
o
Removal of the assembly for cleaning should not require that the furnace be
moved;
o
The male ends of the sections must be oriented towards the appliance so that
falling dust and condensation stay inside the pipe;

A straight flue pipe assembly offers the least restriction to gas flow and results in
stronger draft. Straight assemblies also need less maintenance because there
are no corners to collect creosote;

The use of 45° elbows is strongly recommended;
o
A 90° elbow = 5’ (152 cm), a 45° elbow = 2.5’ (76 cm);
