30 This type of installation can cause non-warrantable problems with components and poor operation of the boiler due to the recirculation of flue products. Multiple vent caps installed in the same horizontal plane must have a 4 ft clearance from the side of one vent cap to the side of the adjacent vent cap(s). Combustion air supplied from outdoors must be free of particulate and chemical contaminants. To avoid a blocked flue condition, keep the vent cap clear of snow, ice, leaves, debris, etc. WARNING: No substitutions of flue pipe or vent cap material are allowed. Such substitutions would jeopardize the safety and health of inhabitants. The stainless steel flue direct vent cap must be furnished by the boiler manufacturer in accordance with its listing (sales order option D-15). Outdoor Installation Outdoor models must be vented with listed vent material per the following instructions and installed with the optional factory-supplied outdoor vent kit. A special vent terminal is provided in accordance with CSA requirements. These must be installed as illustrated in Fig. 25. Care must be taken when locating the unit outdoors, because the flue gases discharged from the vent cap can condense as they leave the cap. Improper location can result in damage to adjacent structures or building finish. For maximum efficiency and safety, the following precautions must be observed: 1. Outdoor models must be installed outdoors and must use the outdoor vent cap available from the manufacturer (sales order option D-11). 2. Periodically check venting system. The unit’s venting areas must never be obstructed in any way and minimum clearances must be observed to prevent restriction of combustion and ventilation air. Keep area clear and free of combustible and flammable materials. 3. Do not locate adjacent to any window, door, walkway, or gravity air intake. The vent must be located a minimum of 4 ft horizontally from such areas. 4. Install above grade level and above normal snow levels. 5. Vent terminal must be at least 3 ft above any forced air inlet located within 10 ft. 6. Adjacent brick or masonry surfaces must be protected with a rust-resistant sheet metal plate. Freeze Protection NOTE: The vent cap must be furnished by the boiler manufacturer in accordance with its listing (sales order option D-11). NOTE: Condensate can freeze on the vent terminal. Frozen condensate on the vent terminal can result in a blocked flue condition. Fig. 25: Outdoor Venting Model No. Size (in.)

Table P: Outdoor Vent Terminals The Raypak electronic temperature control includes a freeze protection feature. In the event the temperature drops below 40°F at any of the temperature sensors, the pump is turned on and will remain on until the temperatures at all sensors rise to 45°F. 31 Controls CAUTION: This appliance has provisions to be connected to more than one supply source. To reduce the risk of electric shock, disconnect all such connections before servicing. WARNING: Installation, adjustment and service of controls, including timing of various operating functions, must be performed by a qualified installer, service agency or the gas supplier. Failure to do so may result in control damage, malfunction, property damage, personal injury, or death. WARNING: Turn off the power to the boiler before installation, adjustment or service of any controls. Failure to do so may result in board damage, malfunction, property damage, personal injury, or death. High Limit — Manual Reset This boiler is equipped with a fixed-setting manual reset high limit temperature device as standard or it may have an optional adjustable setting manual reset high temperature device. The fixed-setting manual-reset high limit is located on the outlet pipe of the heat exchanger on the left side of the boiler (accessible through the front door for reset as necessary). CAUTION: Risk of electric shock: More than one disconnect switch may be required to de-energize the equipment before servicing. Ignition Control Functions When there is a call for heat, the combustion air blower starts to purge air from the combustion chamber. After the pre-purge, the igniter is energized. The standard ignition module will lock out after failing to light four times or after losing flame three times during a single heat demand. To reset it, press and release the ESC/RESET button located on the user interface. The control will automatically reset after 1 hour. When in lock out, the control will run the blower for a 1 minute purge cycle. Turning off the power to the heater WILL NOT reset the ignition module. The optional single-try ignition module will attempt to light only one time before locking out. To reset it, press the ESC/RESET button on the user interface. NOTE: Each ignition module is specific t...
