F Featuring Flexibility Installation guide and material checklists Series 3 This guide must only be used by a quali!ed heating installer/service technician. Read all instructions, including the boiler manual and all other information shipped with the boiler, before installing. Perform steps in the order given. Failure to comply could result in severe personal injury, death or substantial property damage. t Connection tee and internal components are supplied with the boiler. t Fill out the material checklist in this guide to ensure you have the tubing or PVC pipe and all components you will need for the condensate piping. INSTALL CONDENSATE PIPING / TUBING AND COMPONENTS t No external drip leg is needed — it is already included in the boiler’s internal gas piping. t Install a union and shutoff valve. INSTALL GAS PIPING t Connect system and DHW circulator wiring to the terminals designated in the boiler manual. t Connect power wiring and control wiring per boiler manual wiring diagram. WIRE THE BOILER t Choose pre-loaded boiler settings, or customize settings for various applications. t Start up the boiler as directed in the manual. Use a combustion analyzer where specified. t Follow the boiler manual instructions to clean the system if needed, then fill and check water chemistry.

VENT & AIR PIPING (see boiler manual for details) Support pipes as described in the manual. per s ¼” r. e p i ile ep Slop ward bo o t t foo Slide the air inlet pipe and vent pipe into the boiler top openings. Just tighten the restraining rings — no messy sealants required. Reducers or adapters are required when the vent / air pipe O. D. is different from the boiler connection diameter (see below). All AL29-4C stainless pipe applications require adapters made by the vent pipe manufacturer. See the material checklist for items required. Ultra boilers can be sidewall vented or vertically vented as shown in the five options below and in the manual. Choose either direct vent (D. V. — requires air pipe for combustion air) or direct exhaust (D. E. — uses inside air) as shown. Make sure the terminations are placed as required in the manual and that air intakes are at least 12 inches above normal snow line.

Z-Vent II direct vent appliance venting Simpson Dura-Vent FasNSeal™ DO NOT use DWV, CPVC or ABS when using concentric vent termination. Use ONLY PVC schedule 40. IPEX PVC concentric terminations utilize PVC pipe/fittings certified to ULC S636. Where ULC S636 compliance is required, use only IPEX System 636 pipe, fittings 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 different vent pipe manufacturers unless using adapters specifically designed for the purpose by the manufacturer. Plastic piping — Do not attempt to connect different types of plastic piping together. DO NOT use cellular core pipe. All vent and air pipes require a bird screen at each termination where specified in the manual or vent supplement.

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 pressure 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 compliance, 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.

RETURN TO WATER PIPING ITEMS Electrical components Wiring materials and fused shut-off switch Zone valves and other system control devices, as required Carbon monoxide detector, when required Antifreeze, when required Use only antifreeze listed in Ultra boiler manual as suitable for use with Ultra Gas boilers (antifreeze is available from Weil-McLain) — Ask your Weil-McLain distributor for information or visit us online at www.weil-mclain.com to review Ultra literature for recommendations. Ventilation openings Louvers for ventilation openings, when specified in boiler manual 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 Wall mounting option 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.
