Installing the Igniter
Verify the gap between the center electrode and grounding rod is no
less than 1.5mm and no more than 2.0mm.
Install the igniter into the opening opposite to the flame supervision in
the rear cover.
CAUTION: Do NOT apply any assembly compound to the threads of the
igniter. You can cause bad grounding of the spark plug if you apply grease
to it. Bad ground of the spark may result in a weak spark.
Burner Installation
Verify that the wall of the chamber is strong enough to
support the weight of the burner. If necessary, reinforce
the area where you plan to install the burner to support
the weight of the burner.
Refractory furnace walls must allow for thermal expansion as
recommended by the refractory supplier – the wall should
apply no stress on the combustor or refractory layer
surrounding the combustor. Expansion joints built into the
furnace wall shall permit the furnace shell, combustor or
burner block surrounding the combustor to move as a unit in
the event of unequal expansion in the refractory wall and
furnace shell.
The combustor shall not extend beyond the inside of the
furnace wall more than 1”. Beyond this length it is necessary
to add a spacer on the outside of the furnace to keep the
end of the combustor within 1” of the furnace wall.
CAUTION: If the combustor is shorter than the furnace wall thickness the
combustor should be recessed into the wall. To prevent refractory
overheating, a 45° chamfer should be applied.

Algas-SDI Operation and Maintenance Manual - VH100-VH200 2-8
Alloy Combustor
Verify the gasket that was supplied with the burner is
installed between the burner and the chamber wall.
Verify the gasket does not leak.
Check the size of the clearance between the furnace wall
and combustor. If the gap around the firing tube and furnace
chamber is larger the ½”, then pack the gap with ceramic
fiber.

are properly installed. This includes verifying that all
switches are installed in correct locations and all wiring,
pressure and impulse lines are properly connected.
Verify components of spark ignition system are installed and
functioning properly.
Verify that the blower rotates in the correct direction. If
incorrect, have a qualified electrician rewire the blower to
reverse its rotation.
Verify all valves are installed in the proper location and
correctly orientated relative to the gas or air flow direction.
Prepare for Start Up/Adjustment
After installation of the burner system components is complete, the
following shall be followed to prepare for adjustment:
Close all the burner shut-off valves.
Try to light a burner before the purge and other timing relays
have finished their cycles. Verify that the flame monitoring
system indicates a flame failure.
Trip pressure switches and other limit interlocks. Verify that
the main gas valve train closes.
DANGER: If simulated limits or simulated flame failures do not shut
down the fuel system with the required failure response time,
immediately correct the problem and retest before proceeding.
