GAS FIRED BOILERS
Draft hood installation
Attach draft hood to flue collector hood using #10 x 1/2" sheet
metal screws provided. Use boiler cement furnished to provide
gas tight seal.
Failure to maintain gas-tight seal can cause flue gas
spillage and carbon monoxide emissions, resulting
in severe personal injury or death.
Do not alter boiler draft hood or place any obstruc-
tion or non-approved damper in the breeching or
vent system. CSA certification will become void.
Flue gas spillage and carbon monoxide emissions
will occur causing severe personal injury or death.
Draft hood
Spill switch installation
and
switch to draft hood as shown on page 34, Drawing Ref. Letter "K".
Connect wires as shown in the appropriate Control Supplement.
Damper installation
If damper will be installed, see Control Supplement for informa-
tion.

Breeching erection

Connect from draft hood or damper outlet to chimney or vent
with same size breeching. Where possible, vertical venting to the
outside from draft hood or damper outlet will offer best perfor-
mance. Where horizontal breeching is used, slope upward at least
1/4 inch per lineal foot toward chimney or vent and support with
hangers to prevent sagging.
A vertical height of 3 feet to 5 feet of breeching before
any elbow or horizontal breeching is recommended
to reduce chances of flue gas spillage at draft hood
on EGH-95 thru -125 boilers (not restricted on any
EG or EGH-85). Long horizontal breechings, exces-
sive numbers of elbows or tees, or other obstructions
which restrict the flow of combustion gases should
be avoided.
Breeching must not be connected to any portion of a mechanical
draft system operating under positive pressure.
