Maintained Inspection
The homeowner and service per-
sonnel must, at all times, be alerted
for these items:
1. Gas odor.
a) Open the windows.
b) Do not touch any electrical
switch.
c) Extinguish any open flame,
if possible.
d) Shut off the main gas valve.
e) Call the gas supplier.
2. Excessive heat, odors, smoke,
unusual noise. Shut off gas to
all appliances and call gas sup-
plier or Fire Department and
service organization.
3. Keep area around the boiler
clean and free from combustible
materials, gasoline and other
flammable vapors and liquids.
4. Make allowances and maintain
free flow of combustion and
ventilating air.
Freeze Protection
If the boiler is taken out of service
during potentially freezing weather,
always DRAIN IT COMPLETELY
since any water left in the boiler or
pipes can freeze and cause dam-
age. Be sure to open drain cocks on
the wet legs of the left and right
castings, see Fig. 1.
