Measured between tap“B” and the combustion chamber as shown on page 11.
3
At the inlet to the proportionator.
4
Under certain conditions, up to 5 psig (345 mbars) is allowable on RM 300 and larger burners; contact the factory for details.
5
At the inlet to the pilot cock.

6.0 Maintenance
Maintenance Program
A sound preventative maintenance program, carried out by qualified individuals,
will greatly increase equipment reliability and productivity. Frequency of mainte-
nance checks should reflect the duty cycle of the heating equipment and condi-
tions such as dirt and temperature. Any maintenance program should include at
least the following steps:
Check Pressure Settings
Check burner high and low fire air and gas settings.
Check Filters
Examine and, if necessary, clean or replace air and gas filter elements.
Check Pipes for Leaks
Check all piping connections for leaks.
Check Flame Supervision Equipment
Check the ability of the flame supervision system to function properly by simulat-
ing system failures:
Simulate burner flame-out by manually shutting off the gas.
Trip out pressure switches and other limit interlocks.
Try to light the burner before the purge and other timers have finished their cycles.
If simulated limit or flame failures do not shut down the fuel system within an ac-
ceptably short period of time, immediately take the equipment out of service and
correct the problem.
Leak test automatic and manual reset fuel valves per insurance company procedures.
Check Bolts & Screws
Check all bolts and screws for tightness.
Check for Overheating
Check the area around the burner mounting flange for signs of overheating.
Gasket or insulation replacement may be necessary.
