INDUSTRIAL COMBUSTION EQUIPMENT AND VALVES
Maxon practices a policy of continuous product improvement. It reserves the right to alter specifications without prior notice.
Read complete instructions before proceeding,
and familiarize yourself with all the system's equip-
ment components. Verify that your equipment has
been installed in accordance with the original manu-
facturer's current instructions.
CAUTION: Initial adjustment and light-off
should be undertaken only by trained and
experienced personnel familiar with combus-
tion systems, with control/safety circuitry, and
with knowledge of the overall installation.
Instructions provided by the company and/or
individuals responsible for the manufacture
and/or overall installation of complete system
incorporating Maxon burners take precedence
over these provided by Maxon. If Maxon
instructions conflict with any codes or regula-
tions, contact Maxon Corporation before
attempting start-up.
For initial OVENPAK
®
 Burner start-up:
1. Close all burner fuel valves and cocks. Make
preliminary adjustments to fuel gas regulators.
Remove pilot and main gas regulator’s adjusting
screw covers. Turn adjusting screw down (clock-
wise) to approximately mid-position. Close pilot
gas adjustable orifice screw by turning in clock-
wise until it stops. (Do not over-tighten.) Then
back out the adjustable orifice (counter-clockwise)
approximately 2-3 turns.
2. Check all electric circuitry. Verify that all control
devices and interlocks are operable and function-
ing within their respective settings/ranges. Be
sure all air and gas manifolds are tight and that
test ports are plugged if not being used.
3. Check that all duct and chamber dampers are
properly positioned and locked into operating
positions.
4. Disconnect the automatic control motor’s
linkage from the “400” OVENPAK
®
 Burner’s
operating crank arm by loosening the control
motor’s connecting rod from the burner’s toggle
linkage.
For Model EB-MRV and Model “200”
OVENPAK
®
 Burners, the connecting linkage on
the separate control valve must be similarly
loosened and disconnected. Refer to specific
adjusting procedures relating to control valve
adjustment in Maxon catalog.
Initial start-up adjustment should only be
accomplished during a manual burner control
mode.
5. Start all system-related fans and blowers.
Check for proper motor rotation and impeller
direction. Verify that all control interlocks are
working. Allow air handling equipment to run for
adequate purge of your manifolds and combus-
tion chamber plenums. With main gas shut off,
manually advance burner to high fire position so
that air only flows through burner and combustion
chamber.
CAUTION: Do not by-pass control panel timers
typically controlling sequential operations.
For EB OVENPAK
®
 Burners only (step 6)
6. Verify differential air pressure. With combustion
air blower on, all volume air fans operating, and
burner at high fire position, connect a manometer
between the air test connection on backplate of
OVENPAK
® 
Burner and your combustion chamber
static pressure test connection. This will give a
direct differential air pressure reading.
