CHECKING EQUIPMENT BEFORE YOU INSTALL CONTENTS TOPIC PAGE Inspect the unit completely upon receipt from the General Safety Warnings and Codes freight carrier before signing the bill of lading. Locations and Clearances Inspect the appliance and all accompanying parts Electrical Requirements for signs of impact or mishandling. - Page 3 IMPORTANT SAFETY NOTE It takes only 5 seconds of skin contact with 140°F water to cause a second degree burn! You must protect against high water temperatures at all lavatories, tubs, showers and other points of hot water contact. Accidental scalding from high water temperatures is a greater risk in some types of installations.

Page 6: Venting
VENTING OPTIONS ® Gas vents and combustion air ducts connected to PRIMERA products may terminate either above the roof surface or through the side wall. The product may also be equipped with an optional venting system suitable for outdoor installation. - Page 7 Through-the Wall Vent Termination (Category III) The product uses the positive pressure generated by the burner system blower to push combustion products out of the vent. Vent materials may be a stainless steel suitable for exposure to condensate or shall be of the insulated type. The vent system must be certified for use with an appliance requiring a Category III, pressurized vent system.

The combustion products outlet must be located at least 4 feet (1.22 m) below, 4 feet (1.22 m) horizontally from or 1 foot (0.3 m) above any door, window, walkway or gravity air inlet to the building. The outlet must be located at least 10 feet (3.05 m) away from any forced air inlet and at least 3 feet (0.91 m) outside any overhang. - Page 10 Gas Connection Safe operation of unit requires adequate gas supply with the required static and dynamic (flow) pressures. Actual piping selection depends on many variables that must be carefully considered by the gas piping system designer. Do not select gas pipe sizes based only on the supplied tables. These tables are for use by the gas piping system designer as a reference in checking pipe size selections.

Page 13: Boiler Flow Rate Requirements
1600 2000 11.2 ® * Pumps are supplied as standard equipment with PRIMERA water heaters (Model W series). Pumps are not included ® as standard equipment for PRIMERA boilers (Model B series), but may be selected from the optional equipment list. If a Cupronickel heat exchanger is supplied, pump specifications may change. - Page 14 1. Design flow rate is the maximum allowable and recommended flow through the heat exchanger on each individual ® boiler. This flow rate must not be varied on models 1200B, 1600B and 2000B. For all other models of PRIMERA boilers, system designers are strongly urged not to deviate from the design flow rate.

Page 19: Sequence Of Operation - Ignition Control
SEQUENCE OF OPERATION - IGNITION CONTROL POWER-UP Power is applied to the full time 24 volt input. The microprocessor will start a self-check routine of about five seconds. After this delay, the LED will come on and the control is ready to start a new call for heat. For Manual Reset Button Models Only Models of the 35-67 with non-volatile lockout (manual reset button), the microprocessor will check memory to determine if the control should remain in lockout. -
