VENTING THROUGH THE ROOF
When penetrating roof with a 2" PVC vent pipe, a 2" electrical
conduit flashing may be used for a weather tight seal.
Lubricate flexible seal on flashing before PVC pipe is pushed
through the seal. (Field Supplied)
NOTE: No vent cap as shown in Figure 37 is the preferred
method for vertical vent termination in extremely cold
climates.
In extreme climate conditions, insulate the exposed pipe
above the roof line with Armaflex type insulation.
VENT FITTING MATERIAL – STAINLESS STEEL
Gas and liquid tight single wall metal vent fitting, designed
for resistance to corrosive flue condensate such as Type 29-4C
MUST be used throughout.
These fittings and fitting accessories are to be field supplied.
DIRECTION OF STAINLESS STEEL FITTING
All stainless steel fitting must be installed with male end
towards the Furnace.
All horizontal stainless steel sections must be positioned
with the seam on top.
All long horizontal sections must be supported to prevent
sagging.
All pipe joints must be fastened and sealed to prevent escape
of combustion products into the building.
