DANGER: SHOCK HAZARD: Make sure electri- cal power to the heater is disconnected to avoid potential serious injury or damage to components.

Gas Valve Removal

1.Shut off gas supply to the heater. Remove gas pip- ing to gas valve inlet.

2.Disconnect wires, pilot tubing and bleed line, if required.

3.Turn vertical gas pipe from manifold slightly and unscrew gas valve.

4.Reverse above procedure to re-install.

Pilot Removal and Cleaning

2.Disconnect wires at gas valve and slide burner drawer out.

Main Burner and Orifice Removal

1. Remove screws and burner hold down bracket.

NOTE: If the heat exchanger is sooted badly, the burner hold down bracket and spacer can become distorted from direct flame impingement and this usually necessitates replacement of these parts.

2.Lift burners from slotted spacer and slide from ori- fices. Clean with a wire brush.

3.Orifices usually do not need to be replaced. To clean, run either copper wire or wood through ori- fice. Do not enlarge hole. To remove orifice, use a socket wrench and remove the manifold. DO NOT over tighten when reinstalling.
