18. Referring again to Figure #10 , fasten front jacket
panel (#9) in position with sheet metal screws and
install jacket top (#5).
19. Install exhaust assembly with parts 6, 7, and
8. The exhaust cap is made to spring inside the
short length of smoke pipe. A tourniquet made of
wire or a large hose clamp may be used to reduce
the diameter so that it will fit inside the pipe. Two or
three hose clamps in series may be used when a
large one is not available.
ANTIFREEZE
1. Antifreeze added to boilers must be non-toxic and
must be of a type specifically intended for use in closed
hydronic heating systems. Under no circumstances
should automotive antifreeze be used.
2. Use of antifreeze in any boiler may reduce capacity
by 10% or more and increase fuel consumption.
Tankless coil performance will fall as concentration
of antifreeze is increased.
3. Because antifreeze forms slush rather than hard
ice, it is safe to protect only to 10 degrees above
coldest temperature anticipated provided slush
formed can move towards expansion tank.
