Heat Exchanger Cleaning

2.Using the view port, located below the water connections, visually check main burner flames at each start up after long shutdown periods or at least every six months.

WARNING

This area is hot and direct contact could result in burns.

FIG. 4 Burner Flame Patterns

a.Normal Flame: A normal flame is blue, with slight yellow tips, with a well defined inner cone and no flame lifting.

b.Yellow Tip: Yellow tip can be caused by blockage or partial obstruction of air flow to the burner(s).

c.Yellow Flames: Yellow flames can be caused by blockage of primary air flow to the burner(s) or excessive gas input. This condition MUST be corrected immediately.

d.Lifting Flames: Lifting flames can be caused by over firing the burner(s) or excessive primary air.

If improper flame is observed, examine the venting system, ensure proper gas supply and adjust the combustion air.

3.Combustion Air Shutter Adjustment: This appliance uses a fan assisted combustion process. The fan air shutter is factory pre-set and should not need adjustment in most cases. If adjustment is required, the fan air shutter may be manually adjusted to a dimension specified for each model.

4.Flue Gas Passageways Cleaning Procedures: Any sign of soot at the burners indicate a need for cleaning. The following cleaning procedure must only be performed by a qualified serviceman or installer. Proper service is required to maintain safe operation. Properly installed and adjusted units seldom need flue cleaning.

All gaskets on disassembled components must be replaced with new gaskets on reassembly. Gasket kits are available from your distributor.

a.Turn off main power to appliance.

b.Turn off main manual gas shutoff to appliance.

c.Remove the front outer jacket panels.

d.Remove gas valve from the manifold.

e.Remove screws from manifold mounting brackets. Pull manifold(s) / orifice assembly away from burners. Remove hose from burner tap.

f.Remove mounting screws from each burner and slide burner out toward front of appliance. Use caution to prevent damage to burner gaskets, refractory, hot surface igniter or wiring.

g.Remove soot from burners with a stiff bristle brush. Damaged burners or burner gaskets must be replaced.

5.Check the heat exchanger surface for sooting. If present, heat exchanger must be cleaned and problem corrected. Proceed as follows.

a.Remove manifold/orifice assembly as described in steps “a” through “e” in “Burner Removal” in the Installation and Service Manual.

b.Disconnect wiring from hot surface igniter and hose from burner tap.

c.Remove inner combustion chamber door mounting screws, tilt slightly and slide door assembly out toward front of appliance. Use caution to prevent damage to refractory, hot surface igniter, hose and wiring.

d.Check "V" baffles on top of heat exchanger. Remove and clean if necessary.

e.Remove soot from heat exchanger with a stiff bristle brush. Use a vacuum to remove loose soot from surfaces and inner chamber.
