NOTE:

All gaskets/sealant on disassembled components or jacket panels must be replaced with new gaskets/sealant on reassembly. Gasket and sealant kits are available from your distributor.

CAUTION￿

When a Category IV vent system is disconnected for any reason, the flue must be reassembled and resealed according to the vent manufacturer’s instructions.

D. BURNER MAINTENANCE

The burner should be removed for inspection and cleaning on an annual basis. An appliance installed in a dust or dirt contaminated atmosphere will require inspection and cleaning on a more frequent schedule. An appliance installed in a contaminated environment may require cleaning of the burner on a 3 to 6 month schedule or more often, based on severity of the contamination. The fan assisted combustion process may force airborne dust and dirt contaminants, contained in the combustion air, into the burner. With sustained operation, non-combustible contaminants may reduce burner port area, reduce burner input or cause non-warrantable damage to the burner.

Use extreme care when operating an appliance for temporary heat during new construction. Airborne contaminants such as dust, dirt, concrete dust or dry wall dust can be drawn into the burner with the combustion air and block the burner port area. An external combustion air filter is provided with the appliance. The combustion air filter is for Temporary Use Only and MUST be removed when the appliance is placed in normal service. An additional filter is located inside the transition chamber, at the inlet to the combustion air blower, to also prevent particulate matter and small foreign objects from entering the blower and burner. This internal filter should be checked and cleaned on a six month interval or more often in a contaminated environment. See the CombustionAir Blower section of this manual for cleaning instructions. The burner of an appliance used for temporary heat without a combustion air filter installed will probably require a thorough cleaning before the unit is placed into normal service.

BURNER REMOVAL AND CLEANING

Access to the burner will require the following steps:

a.Turn off main electrical power to the appliance.

b.Turn off main manual gas shutoff to the appliance.

c.Remove the outer control panel cover. Open the control panel and remove the screws from the lower front edge of the radiused front outer jacket panel. Lift the edge of the radiused panel and

locate the internal screws attaching the back edge of the radiused panel. Reach through the control panel opening with a 5/16” nut driver and loosen the 2 internal screws holding the rear edge of the radiused panel. Pull the panel slightly forward and remove it. Remove the screws along the front and rear edge of the top outer jacket panel to remove the jacket top. This allows access to the components in the top of the appliance.

d.Disconnect the gas supply connection to the internal gas train at the field installed union.

e.Remove the air inlet pipe connection to the boiler/water heater.

f.Remove the insulation blanket* on top of the heat exchanger. Note: Take care not to tear insulation blanket on removal.

g.Disconnect the blower motor power wires at the connection to the VFD.

h.Disconnect the power wires to the gas valves, flow switch and pressure switches (if equipped). Multiple pin connectors are used at all of these components for ease of service.

i.Remove the sensing tubes from the air ratio gas valve to the combustion air blower.

j.

Remove the 6 nuts holding the blower assembly

 

to the blower and remove the blower assembly.

k.Disconnect the power wire to the hot surface igniter.

l.Remove the hot surface igniter. The hot surface igniter is fragile. Use care to prevent impact damage to the silicon carbide igniter surface when removing the igniter.

m.Remove the 8 nuts holding the burner to the heat exchanger.

n.The burner can now be lifted vertically out of the heat exchanger cavity.

o.Use care to prevent damage to the woven burner port surface on removal.

*Insulation jacket is tucked under the control panel assembly and cannot be “removed” without removing the control panel.
