siding should rise 14” above corner 
posts all around. See Fig. 4. 
Now we will return to heater: See that 
lower heater pipe E is 1%” into heater 
pipe F. Now with wet asbestos cement 
make an air-tight joint where pipe B 
enters pipe F. Now slip on heater box G 
over heater board H, flush at top and back, 
and fasten with two screws on each side. 
Now slip one of C over top of heater 
pipe F and nail down to top of heater 
box. Slip remaining C over bottom of 
heater pipe F and nail to bottom of heater 
box. 
You will notice that the board on right 
side of heater is 1” shorter than the other 
three, which provides a hole for ventilation. 
Now slip remaining B over heater pipe 
E at left end of incubator and nail down 
securely. 
Now, with asbestos cement fill in notch 
all around heater pipes at each end of 
incubator and the space between heater 
and incubator above upper cross-piece on 
back of heater. Also put enough of the 
cement on top of heater to come up within 
1%” of top of heater pipe F. To aid you
