Propane applications

Ultra-80 can be ordered as propane or you can obtain

the Ultra-80 propane conversion kit.

For Ultra-80 at altitude up to 5,500 feet, use

W-M p/n 383-501-020.

All other Ultra boilers are shipped with items needed to

set up the boiler for propane, for altitude up to 5,500 feet.

High altitude propane, Ultra-80 only — For altitude

above 5,500 feet, all Ultra boilers require a high-altitude

propane conversion kit. The Ultra-80 must ﬁrst be

equipped for propane (either purchased as Ultra-80LP or

converted to Ultra-80LP using the kit listed above).

Ultra-80LP 383-500-644

High altitude propane, Ultra-105–399 — For altitude

above 5,500 feet, all Ultra boilers (except Ultra-399)

require a high-altitude propane conversion kit. Obtain

the kit listed below:

Ultra-105 383-500-645

Ultra-155 383-500-646

Ultra-230 383-500-647

Ultra-299 383-500-648

Weil-McLain Ultra wall-mounting kit, p/n 389-900-180

Recommended equipment

Use a combustion analyzer to verify boiler operation,

following the instructions in the Ultra boiler manual.

U-tube manometer for checking gas line pressure

Volt-ohmmeter may be required for troubleshooting

Equivalent feet for elbows — deduct from maximum equivalent length of piping:

• 7 feet per for each 4-inch elbow & 2 or 3-inch 90° long-radius or 45° elbow

• 16 feet for each 2- or 3-inch short-radius elbow

a — Use 3"x2" reducer at boiler b — Use 3”x2” PVC reducers at termination

c — Use 4”x3” reducer at boiler d — Use 4"x3" PVC reducers at termination

Stainless (AL29-4C) vent pipe — install an adapter at the boiler for all applications. Also install an

adapter at the termination unless using separate-pipe termination.

** Ultra-80 and 105 boilers installed with 2-inch vent piping automatically derate due to the pres-

sure loss in the vent and air piping. The derate ranges up to 10% for the Ultra-80 at 100 feet or

15% for the Ultra-105 at 100 feet.

Note 1: IPEX 3” and 4” PVC concentric vent kits can be used with standard PVC pipe, ﬁttings and

cement (ANSI/ASTM D1785) except where ULC S636 compliance is required. For ULC S636 compli-

ance, all pipe, ﬁttings and cement must be IPEX System 636. When using IPEX kits, use only IPEX

product code 196006 for 3” venting or IPEX product code 196021 for 4” venting.

Note 1: DO NOT use DWV, CPVC or ABS when using concentric vent ter-

mination. Use ONLY PVC schedule 40.

Note 2: IPEX PVC concentric terminations utilize PVC pipe/ttings certied

to ULC S636. Where ULC S636 compliance is required, use only IPEX

System 636 pipe, ttings and cement.

AL29-4C vent piping — Install a PVC-to-stainless adapter supplied

by the vent pipe manufacturer at the boiler vent connection and

at the termination (when using Weil-McLain plate or concentric

PVC termination). DO NOT mix piping from dierent vent pipe

manufacturers unless using adapters specically designed for the

purpose by the manufacturer.

Plastic piping — Do not attempt to connect dierent types of

plastic piping together.

DO NOT use cellular core pipe.

All vent and air pipes require a bird screen at each termination

where specied in the manual or vent supplement.
