START-UP AND ADJUSTMENT
INSTRUCTIONS FOR VALUPAK®-II
BURNERS
Instructions provided by the company or individual
responsible for the manufacture and/or overall installation
of a complete system incorporating MAXON burners take
precedence over the installation and operating
instructions provided by MAXON. If any of the instructions
provided by MAXON are in conflict with local codes or
regulations, please contact MAXON before initial start-up
of equipment.
CAUTION
Before initiating the following start-up and
adjustment procedure, it is important that a
check be made to verify that all of the equipment
associated with and necessary to the safe
operating of the VALUPAK®-II burner system has
been installed and piped in accordance with the
"General installation instructions". If the burner
system is part of an oven or other heating unit
which has been purchased as a complete pre-
piped and pre-wired package, it may be assumed
that these instructions have already been carried
out by the individual or company responsible for
the overall installation.
Initial adjustment and light-off should be undertaken only
by trained and experienced personnel familiar with
combustion systems, with control/safety circuitry and with
knowledge of the overall installation.
To start-up a VALUPAK®-II burner for the
first time
1. Close main gas cock. Check tightness of gas piping.
Connect U-tube manometer to burner test connection
on the burner gas nozzle inlet. Note burner type and
required gas pressure (page 6).
2. Establish correct blower direction of rotation of all
fans. See arrow on blower housings.
3. Disconnect automatic control motor wiring to avoid
unexpected motor travel. Check that gas control
valve is at low fire position (as supplied). For size 150,
300 and 600 control motor rotation is counter clock-
wise when looking towards controls linkage going
from low to high fire. For the size 60 when looking to
the linkage the air butterfly crank rotation is counter-
clockwise. Since the control motor is located at the
opposite side of the linkage its rotation is clockwise
from low to high fire.
4. When operating the burner with LPG instead of nat-
ural gas, the linkage connection on the air valve crank
needs to be changed. In order to do this, unscrew the
nut (M6) at the back of the crank and relocate the link-
age from the hole marked "C1 – NG" to the hole "C3 –
LPG" by slightly rotating the crank and linkage. Screw
the nut back in place. No further modification on the
burner needs to be done. (See Detail C, to the left)
5. Bleed air from the fuel supply line. Remove the cover
from the gas pressure regulator and establish that
regulator is at low end of control range.
