Table 10: Input Rate
(turn adjustment screw counterclockwise to
decrease manifold pressure, or clockwise to
increase manifold pressure).
iii
. Turn on gas valve not having pilot control.
Adjust gas valve pressure regulator to obtain
required manifold pressure. Manifold
pressure may not change during initial turns
of adjustment screw.
3. Clock gas meter for at least 30 seconds. Use Table
10 to determine gas flow rate in Cubic Feet per
Hour.
4. Determine Input Rate. Multiply gas flow rate by gas
heating value.
5. Compare measured input rate to input rate stated on
Rating Label.
a. Boiler must not be overfired. Reduce input rate
by decreasing manifold pressure. Do not reduce
more than 0.3 inch w.c. If boiler is still overfired,
contact your Governale distributor or Regional
Office for replacement Gas Orifice.
b. Increase input rate if less than 98% of Rating
Label input. Increase manifold gas pressure no
more than 0.3 inch w.c. If measured input rate is
still less than 98% of rated input:
i
. Remove Main Burners per procedure in
Section X: Service Instructions.
ii
. Remove gas orifices. Drill one (1) drill size
larger (drill size is stamped on orifice, or see
Key No. 4D in repair parts section).
iii
. Reinstall gas orifices and main burners.
Measure input rate.
6. Recheck Main Burner Flame.
7. Return other gas-fired appliances to previous
conditions of use.
L.
Adjust gas input rate to boiler.
LP/Propane.
1. Set thermostat to highest setting.
2. Adjust tank regulator for gas valve inlet pressure of
13.5 inches w.c. or less.
3. Gas valve has step opening regulator which initially
opens to 1.4 or 2.5 inch w.c. and steps to full
pressure after approximately 30 seconds. Check
manifold pressure after step has occurred. Adjust gas
valve pressure regulator as necessary for 10.0 inches
w.c. (turn adjustment screw counterclockwise to
decrease manifold pressure, or clockwise to increase
manifold pressure). If 10.0 inches w.c. can not be
attained, check gas valve inlet pressure. If less than
11.0 inches w.c., contact gas supplier for assistance.
M.
Clean Heating System (Steam).
A local qualified
water treatment chemical specialist is a suggested
source for recommendations regarding appropriate
chemical compounds and concentrations which are
compatible with local environmental regulations.
1. Oil from new piping connections and sediment in
existing piping must be removed from system to
prevent unsteady water line and carry-over of
entrained water into supply main.
a. Fill boiler to normal waterline.
b. Follow Lighting or Operating Instructions to
place boiler in operation. See Figure 53, 54, 55,
56 or 57.
c. Operate boiler with steam in entire system for
several days to bring system oil and dirt back to
boiler.
d. Drain condensate from drain valve in wet return.
Operate boiler until condensate runs clean.
2. Boil-out boiler.
a. Follow instructions TO TURN OFF GAS TO
APPLIANCE. See Figure 53, 54, 55, 56 or 57.
b. Fill boiler to normal waterline.
c. Remove safety valve.
d. Pour recommended boil-out compound into
boiler through safety valve opening.
e. Reinstall safety valve in Tapping "E" with
spindle in vertical position. See Figures 1 and 2.
