SECTION I

INSTALLATION

A. GENERAL

The Wayne HSG200 and HSG400 power gas

conversion burners are adaptable to most types of

central heating plants previously fired by power oil

burners. Typical heating plants are gravity and forced

air circulation furnaces, hot water, steam or vapor

boilers. Power burner design makes the HSG200 and

HSG400 well suited for “negative draft” fired

appliances where an oil burner is being replaced.

Installation of these power gas conversion burner

models must conform to local codes, or in their

absence, the American National Standard for the

Installation of Domestic Gas Conversion Burners,

ANSIZ21.8 - and the National Flue Gas Code,

ANSIZ223.1 or current standard year.

NOTICE: ANSI or local installation code compliance is

the sole responsibility of the qualified installer.

B. VENTILATION

The HSG conversion burner models covered by this

manual shall not be installed in an appliance located

where normal air circulation or infiltration is limited in

providing all the air necessary for proper combustion

and draft hood dilution air.

In open basements of homes of normal construction

(without basement storm windows or tight stair doors)

infiltration of combustion air is usually sufficient to

replace that drawn up the flue, so special provisions

are seldom necessary.

When the heating appliance is installed in a tightly closed

room without ventilation openings to outdoors, or other

rooms, provisions shall be made for supplying air for

combustion through special openings, one near the floor

line and the other near the ceiling. Each is to be sized

on the basis of one square inch (645.2mm

) or more of

free area each 1,000 BTU (.29kW) input per hour.

When the building is of unusually tight construction, has

kitchen and/or bathroom ventilation fans which may be

used for exhausting air to outdoors, or has a vented

fireplace, it is recommended that combustion air be

supplied to the furnace room through intakes extending

to the outside of the building and terminating in down

turned fittings, suitably arranged to prevent obstruction

from snow or rain, and including a protecting screen not

smaller than 1/4 inch (6.35mm) mesh.

C. HEATING APPLIANCE INSPECTION

Clean the appliance heat exchanger interior,

combustion chamber and flue connections. Remove

all adhering tars, scale, dirt and soot. Inspect the heat

exchanger for obvious and potential flue gas leaks.

Cement all joints around the appliance base and

access openings to prevent air and/or flue gas leakage

into or out of the combustion chamber.

Warm Air Furnaces* - Make certain the electrical

characteristics of the fan and limit switch correspond to

those required by this burner and that they are in

proper working order.

Hot Water Boilers* - Make certain water temperature

and altitude gauges, pressure relief valves are in

proper working order.

Steam Boilers* - Make certain the system is pressure

tight, and that the pressure gage and pop off safety

valve are in proper working order. Existing water sight

glass permits clear observation of boiler water level.

*Where applicable, existing temperature of pressure

limit switch or low water cut-off switch operation and

electrical characteristics shall be checked to determine

their compatibility to the gas control circuitry of this

burner.

D. CHIMNEY, FLUE PIPE AND DRAFT CONTROL

The chimney should be inspected for unsafe

conditions such as excessive soot accumulation,

deteriorated masonry, blockage or potential blockage.

NOTICE: No manually adjustable flue pipe damper is

permitted on any gas burner installation.

The chimney should be lined with a corrosion resistant

material. If the chimney is unlined, consult your local

gas utility for recommendations.

WARNING: Under no circumstances should the flue

pipe be connected to the chimney of an open fireplace.

The flue pipe should be sized to carry of the flue gases

as outlined in Figure 1.

Figure 1

Strict compliance to appropriate codes should be made

regarding flue pipe clearances from combustible materials.
