Monitor the system circulator. This system circulator aids in the pumping of water. If the release of water is not sufficient then it must have an issue with the circulator. If the circulator is damaged you will hear the bubbling noise from the boiler or the system will start switching on and off. If there is a gas smell in your house avoid turning on any gas or electrical appliance. It may result in an explosion. Call gas suppliers on an urgent basis.

What are the common problems with your Weil McLain boiler? The common issues with your Weil boiler may be from the given below. No heat If the thermocouple of the boiler is burnt then it is the main reason your boiler is not responding to the heat. A little bit of heat If the water pressure is not accurate or insufficient then it means that water cannot get enough supply and hence no hot water. How to know the water is insufficient in the boiler?
It can be easily detected the water in the boiler is low if it starts releasing rattling sounds. Cycles regulation If the set temperature of your house is inappropriate then it is noticeable that the cycle is turning on and off over time. Unequal distribution of heat If there is a fault in the zones of the boiler. Alarm triggered Always set an alarm triggering for carbon monoxide.

Figure 3 Combustion and ventilation air openings. Depending on the model, this boiler is capable of achieving combustion efficiencies up to In addition, the 88 Series 2 can achieve thermal efficiencies up to When it comes to versatility, the 88 Series 2 is in a class of its own. Best of all, it can achieve this backward compatibility without consulting Weil-McLain.
It includes:. Make final adjustments Dimensions and ratings Handling ceramic fiber and fiberglass materials The following defined terms are used throughout this manual to bring attention to the presence of hazards of various risk levels, or to important information concerning the life of the product.
Indicates presence of hazards that will cause severe personal injury, death or substantial property damage if ignored. Indicates presence of hazards that can cause severe personal injury, death or substantial property damage if ignored. Indicates presence of hazards that will or can cause minor personal injury, death or substantial property damage if ignored.
Indicates special instructions on installation, operation or maintenance that are important but not related to personal injury. Failure to follow all instructions in proper order can cause severe personal injury, death or substantial property damage.
Do not use petroleum-based cleaning or sealing components in boiler system. Severe damage to system components can result, causing substantial property damage. Check for nearby connections to:. System water or steam piping. Venting systems - see page Combustion and ventilation air supply — see "Provide combustion and ventilation air supply openings" on page 4. Check area around boiler.
Remove any combustible materials, gasoline and other flammable vapors and liquids. Failure to keep boiler area clear and free of combustible materials, gasoline and other flammable liquids and vapors can result in severe personal injury, death and substantial property damage. Floor construction and condition must be suitable for weight of boiler when filled with water. See page 34 for approximate boiler operating weight. A level concrete or brick foundation constructed per Table 1 and Figure 1 is required when:.
A floor could possibly become flooded. Singlewall vent pipe — 18 inches. Doublewall vent pipe — refer to vent pipe manufacturer's recommendations for vent pipe clearances. See burner literature for length and recommended service clearances.
Do not install an exhaust fan in boiler room. Adequate combustion and ventilation air must be provided to assure proper combustion and prevent possibility of flue gas leakage and carbon monoxide emissions, causing severe personal injury or death. Opening sizes must comply with state, provincial or local codes. In their absence, use the following when boiler is in a confined room:.
Minimum dimension of each opening is 3 inches. When all air is taken from outdoors, each opening should connect directly or by ducts from outdoors or crawl or attic spaces that freely connect with outdoors and sized as listed below:. Refer to their manufacturer's instructions for size. If unknown, use:.
Lock louvers in open position, or interlock with equipment to prove open before boiler operation. When combustion and ventilation air enters through sidewall openings, ensure openings comply with Figures 2 and 3.
Figure 2 Combustion and ventilation air openings — Boiler room below grade. Figure 3 Combustion and ventilation air openings — Boiler room partially or completely above grade. Remove top jacket panels. Set aside until after boiler is piped. The boiler contains ceramic fiber and fiberglass materials. Use care when handling these materials per instructions on page 38 of this manual.
Failure to comply could result in severe personal injury. Remove lag screws 2 in front, 2 in rear from shipping rails. Remove boiler from skid. Cables are already attached to block assembly. See Table 2 for lifting weight.
Raise boiler off skid. Use pipe rollers under skid angles to roll boiler. Place boiler in final position. Center boiler on foundation, if used. Level boiler. Shim under skid angles, if necessary. Cables are not intended for long-term usage. Cables may corrode inside boiler, weakening their lifting strength. Failure to remove cables can result in severe personal injury, death or substantial property damage.
Inspect block assembly for disjointed sections. Check gas-tight seal of flue collector hood and cleanout plates. Gas tight seal must be maintained to prevent possible flue gas leakage and carbon monoxide emissions, resulting in severe personal injury or death. Check inside section assembly for any light passing through unsealed areas. At unsealed areas, check for:. Correct all conditions and repeat step b. If unsealed areas still exist, contact your Weil-McLain distributor or sales office before continuing installation.
Proceed to "Perform hydrostatic pressure test," page 8. Use pipe rollers under steel skid. Sections are top heavy. Unbolted sections may fall if not supported, resulting in severe personal injury or death. Lay back section on floor with ports face up. Press blanket against back target wall as shown in Figure 4. Using knife, cut hole through blanket to expose observation port opening.
See Figure 4. Do not get any adhesive on machined port surfaces. Around curves, grasp at 1" intervals and push together. Do not stretch. Do not pre-cut rope. Gas tight seal must be maintained to prevent possibility of flue gas leakage and carbon monoxide emissions, causing severe personal injury or death.
Remove any grit from port machined surfaces with clean rag. Do not use petroleum-based cleaning or sealing compounds in boiler system. If sealing ring slips out of groove, stretch ring gently for several seconds, then reposition in groove. Refer to Figure 5. Do not apply silicone sealant on, next to or under sealing ring. Silicone sealant applied as specified above prevents unburned oil vapors from coming in contact with sealing ring.
Vapor contact can damage rings, resulting in severe damage to boiler and substantial property damage.
