Chimney

Be sure that the chimney is sufficiently high and large enough to meet the specifications of the burner unit installed. Check that there is sufficient draft for the proper burning of oil. At least -0.015 in. w.c. (-0.004kPa) of over-fire draft is recommended.

Blocked Vent Safety Switch

Oil-fired water heaters must be fitted with the blocked vent safety switch supplied with your heater. The installation pro- cedure is given below. For further details and information refer to the instruction sheet supplied with the switch. (Not required for JWF307V.)

Installation

1.Pierce a 16mm (5/8 in.) dia. hole into the flue pipe 305mm to 457mm (12 to 18 in.) from the breech con- nection of the water heater. Remove one of the securing nuts from the pipe of the safety switch. Tighten the other securing nut onto the pipe as far as possible.

2.Insert the threaded pipe end into the pierced hole, then install the securing nut, which was removed in step 1, and tighten securely.

CAUTION:: Turn "OFF" the electrical supply to the water heater when wiring safety switch.

3.Wire the safety switch in series with L1 of the electrical supply (see Figures 9, 10 & 11). Install and route wiring in an accordance with “Canadian Electrical Code Part 1 (C22.1)” and any applicable local codes.

CAUTION: If for any reason the system has shut down during operation, the cause of the system failure should be investigated and corrected before resetting the safety switch and re-starting the system.

Power Venting

Models JWF307, JWF507 and JWF657 may be power vent- ed with a Field SWGII 4HD Power Venter. The following control kits may be used with the SWGII 4HD:

CK 61 Electronic Post Purge.

CK 62 Thermally Activated Post Purge.

Installation of Power Venter

The “Installation Code for Oil-Burning Equipment (CSA B139-04)” or “Standard for the Installation of Oil- Burning Equipment (NFPA 31)”, local codes and the man- ufactures instructions should be adhered to in all installa- tions of the water heaters and power venters. A draft regu- lator must be used in conjunction with the installation of the power venter (see “Draft Regulator”). Consult the applicable codes to calculate the equivalent length of pipe for each fit- ting in the vent system. Add this (equivalent) length to the length of the straight runs of pipe to determine the total equivalent vent pipe length.

THE MAXIMUM RECOMMENDED RATE OF

0.75GPH, THE FLUE BAFFLE MUST BE ALTERED AS IN THE DIAGRAM. BOTH HALF DISCS MUST BE BENT FLAT AGAINST THE BODY OF THE BAFFLE.

THIS IS REQUIRED TO ALLOW FLUE GAS

PASSAGE AT THE HIGHER FIRING RATE.

Water Supply

Piping Installation

Piping, fittings, and valves should be installed according to the applicable installation drawing (Figures 7 & 8). A pres- sure-reducing valve and/or an expansion tank may be required for installations where the water pressure is high. The pressure-reducing valve should be located on the sup- ply to the entire house in order to maintain equal hot and cold water pressure.

Important:

Do not apply heat to the water fittings on the heater as they may contain nonmetallic parts. If solder connections are used, solder the pipe to an adaptor before attaching the adaptor to the hot and cold water fittings.

Some models may contain energy saving heat traps to prevent the circulation of hot water within the pipes. Do not remove the inserts within the heat traps.
