Raypak Tube Cleaning KIT

GAS VALVE REMOVAL

1.Shut off gas supply to the heater. Remove gas piping 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.

MAIN BURNER AND ORIFICE REMOVAL

1.Remove burner drawer. See burner drawer removal procedure.

2.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 neces- sitates replacement of these parts.

3.Lift burners from slotted spacers and slide from orifices. Clean with a non-sparking wire brush.

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

PILOT REMOVAL AND CLEANING

1.Remove burner drawer. (See burner drawer removal procedure).

2.Disconnect pilot tubing, disconnect wires from gas valve.

3.Disconnect pilot bracket from burner shield.

4.Remove pilot from bracket.

5.Remove pilot orifice and air opening, and clean with wire or small brush. CAUTION! DO NOT enlarge hole in pilot orifice.

6.Reverse above procedure to re-install.

HEAT EXCHANGER REMOVAL

1.Shut water, gas and electricity off, close valves and relieve pressure, remove relief valve.

Remove side inspections panels.

2.Remove top holding screws.

3.Remove draft diverter, lift and remove top and flue collector. Remove inspection panels.

4.Loosen bolts and disconnect flange nuts on inlet-outlet header, loosen union(s) at gas pipe and slide heater away from piping until stud clear the header.

5.Remove heat exchanger corner brackets.

6.Remove combustion chamber clips at the four corners of the heat exchanger.

7.Lift heat exchanger straight up using caution not to damage refractory.

8.Reverse above procedure to reinstall.

TUBE CLEANING PROCEDURE

Establish a regular inspection schedule frequency, depending on local water condition and severity of service. Do not let the tubes clog up solidly. Clean out deposits over 1/16” in thickness.

The heater may be cleaned from the right side, without breaking pipe connections. It is preferable, however, to remove both headers for better visibility through the tubes and to be sure the ground-up lime dust does not get into the system.

Note that you do not remove the top panel or the heat exchanger, generally.

After reaming, mount the wire brush in place of the auger and clean out debris remaining in the tubes.

Another method is to remove the heat exchanger, ream tubes and immerse heat exchanger in non-inhibited de-scale solvent for severe scale build up.

TUBEREPLACEMENTPROCEDURE

On Raypak units, tube replacement may be effected without rolling as a temporary means or repair, providing there are two or more tubes rolled in to act as stays on the left and right side. The “O” rings should provide a seal up to 120 PSI working pressure.

Use 3/8” heavy duty reversible drill motor or larger to power the tube roller. If a reversible drill is not available, after rolling the tube in, remove the drill motor and wrench out the roller. A tube roller is available from the factory.
