Burner
Proper maintenance of the burner is critical for
efficient trouble-free operation. The burner of
every Campo heater is tested before shipment,
however,
changes
in
altitude,
fuel,
temperature, and humidity will affect the
performance and efficiency of the burner. Also,
the burner should be checked at least annually
(preferably before the start of the heating
season) for efficient burning.
1. Shut
the
system
down
totally,
disconnecting or locking out power supply
so there can be no accidental start-up
during inspection.
2. Inspect the burner carefully, including
upstream and downstream sides of mixing
plates as well as burner body face. Any
accumulation of scale or foreign material on
either side of the mixing plates should be
removed with a wire brush. Check visually
that no holes in the mixing plates are
blocked. If any burner ports are plugged
(even partially) clear them with a piece of
wire or a #47 drill bit (2mm).
WARNING
Do not enlarge burner ports or performance
may be drastically affected.
If any mixing plates are loose or missing
fasteners, tighten/replace as necessary.
Always use zinc plated or stainless fasteners.
3. Observe flame pattern and, if necessary,
take steps to correct obstructed ports. The
velocity and distribution of the air across
the burner is pre-set at the factory and
should be changed by authorized service
personnel only.
Igniter
To start ignition, the igniter must be adjusted
properly and must not be damaged or
defective. Periodically the igniter should be
inspected
for
damage,
corrosion,
and
separation. To inspect and adjust the igniter,
use the following procedure:
1. Remove the igniter from the burner.
2. Visually inspect the igniter for corrosion and
damage to the insulator and tip.
3. Consult the Specification Sheet for proper
spacing and position.
Pressure Regulator
WARNING
Unqualified service personnel must not
make any adjustments on the regulators!
The pressure regulator on the manifold
functions to reduce the supply of gas to the
burner. There is one pressure regulator on the
main line.
To adjust the main line regulator pressure,
remove the cap of the regulator; then either
turn the adjusting screw out to decrease
pressure or turn the adjusting screw in to
increase pressure. Do not make any
adjustment on the regulators without knowing
what you are doing and having the proper
gauges attached. Also, do not bottom the
adjusting screw.
The heater is designed to operate with a line
pressure upstream of the Maxitrol RV81, of
10 to 14 W.C. (2.24kPa to 3.48kPa). For
maximum
efficiency
and
safety,
the
regulator must not be adjusted above this
pressure. The Belimo or RTC modulating
valve varies the gas flow of gas to the
burner to maintain the pre-set discharge air
temperature and has been set at the factory
for
optimum
performance.
Field
adjustments are not required.
CAUTION:
Damaged or defective regulators
must be replaced. Also, never exceed the
pressure specifications listed.
