Start-Up
Checking Unit Heater Rate
Table 6.
Type of Gas Natural
NOTICE:
Overfiring!
Never overfire the unit heater, as this could cause
unsatisfactory operation, or shorten the life of the
heater.
Gas appliances are rated based on sea level operation,
with no adjustment required at elevations up to 2000 feet
(610 m). At elevations above 2000 feet (610 m), input
ratings should be reduced by 4 percent for each 1000 feet
(305 m) above sea level. Check the input rate as follows:
1. Turn off all other gas appliances that utilize the same
gas meter as the unit heater.

125

200
3. Using the gas meter, clock the time that it takes to burn
one cubic foot of gas (Heating Value).
225
4. Insert the time, in seconds, into the formula below:
250
Heating Value (Btu/ft3) (3600 s/hr)
Time (s/ft3)
Example: If the heating value = 1000 BTU/ft3 and the time/
ft3 = 18 s/ft3 then
Input Rate =
(1000 BTU/ft3) (3600 s/hr)
18 s/ft3
Input Rate = 200,000 BTU/hr
(Refer to “General Safety Information,” p. 7 for metric
conversions.)

Note: When installed in Canada, any references to deration at altitudes in
excess of 2000 feet (610 m) are to be ignored. At altitudes of 2000
to 4500 feet (610 to 1372 m), the unit heaters must be orificed to
90 percent of the normal altitude rating, and be so marked in
accordance with the CSA certification.
(a) This schedule is for units operating at normal altitudes of 2000 feet
(610 m) or less. SPECIAL ORIFICES ARE REQUIRED FOR INSTALLATIONS ABOVE 2,000 FEET (610 m).
Primary Air Shutter Adjustment
After the unit has been operating for at least 15 minutes,
adjust the primary air flow to the burners. Turn the frictionlocked, manually-rotated air shutters clockwise to close, or
counterclockwise to open (see Figure 20, p. 27 and
Figure 2, p. 8).
For correct air adjustment, close the air shutter until yellow
tips in the flame appear. Then open the air shutter to the
point just beyond the position where yellow tipping
disappears. Refer to Figure 21.
Note: There may be momentary and spasmodic orange
flashes in the flame. This is caused by the burning
of airborne dust particles, and should not be
confused with the yellow tipping, which is a stable
or permanent situation when there is insufficient
primary air.
