Page 7: Jacket Assembly And Control Installation
3.3 JACKET ASSEMBLY AND CONTROL INSTALLATION The boiler jacket has been designed for ease of assembly and removal. The following are step by step instructions. A philips screwdriver, 17mm socket and ratchet, 17mm wrench or adjustable wrench are needed. STEP 1: VERIFY CONTENTS OF JACKET ASSEMBLY PACKAGE. Your jacket assembly will contain boiler block insulation, rear of block insulation, front panel insulation, two (2) side panels, rear panel, top panel, front panel and a fastening package with screws and foil tape for fastening insulation. - Page 8 STEP 2: INSULATION INSTALLATION Drape the large piece of boiler block insulation directly over the block taking care to provide equal coverage on both sides. If installing a 7,8, or 9 section boiler, the extension insulation should be draped over the rear 3 sections of the boiler. Install the rear insulation piece by sliding it over the upper tie rods and around the flue collar as shown.
- Page 9 STEP 4: SIDE PANEL ATTACHMENT CONTINUED Align the left and right panel so the knock out on the side of each panel is located toward the upper front corner of the boiler. Install each side panel by sliding the front mounting holes over the front tie rods.
- Page 10 STEP 6: TOP PANEL ATTACHMENT Affix the top panel by placing the holes located on the underside of the panel over the jacket affixing pins. Press down on the top panel and it will snap in place. Secure the top panel to the back of the side panels with 2 sheet metal screws provided in the hardware packet.

STEP 8: CONTROL MOUNTING Upon completion of the jacket assembly the operating control can be mounted on the side of the boiler where the sensor wire was installed. The jacket side panels have been pre- drilled holes for mounting the control. Follow the mounting instructions and use the hardware provided with the control. - Page 12 Circulation Pump A calculation for proper pump selection must be performed for all installations. The pump(s) should not be operated at maximum working pressures above 30 psi or maximum working temperatures above 200°F and within limits advised by the manufacturer. The pump must not be operated unless the system has been flushed, bled of all air and completely filled with water.

Page 16: Electrical Wiring
5.0 ELECTRICAL WIRING All external wiring must be performed in compliance with existing electrical codes within the local jurisdiction. In Canada, in compliance with the requirements of CSA STANDARD C22.1 and the Canadian Electrical Code. In the USA, in compliance with the requirements of NFPA 70, National Electrical Code. - Page 17 HEATING and Indirect Water Heater IMPORTANT: When installing with an indirect water heater, the Zone/Indirect Switch must be set in the I position. When set in the I position, calls to ZC-ZR will bypass the Thermal Targeting feature and allow the boiler to fire to the high limit setting to heat the indirect tank. The indirect signal must be separate from all heating zone signals.
- Page 18 Typical wiring for line voltage oil burner with Honeywell L7248 and one heating zone. Make sure sensor is inserted ALL THE WAY into the immersion well on top of the boiler. Route sensor wire through clearance hole A and connect it to the L7248 control.

Page 19: Chimney Information
If the masonry, brick, block chimney or tile chimney liner is in poor condition a new chimney liner rated for oil may have to be installed. In the event the condition still exists after installation of a new liner consult Granby. -
Page 20: Fuel System
7.0 FUEL SYSTEM The fuel system piping must comply with the fuel pump manufacturers’ specifications which are included with the burner. In addition, all fuel system piping must comply with local codes and ordinances. • The quality of your fuel oil is of great importance. For most instances your burner is designed to burn clean, water free, #2 fuel oil. -
Page 21: Burner Installation And Setting
COMBUSTION & VENTILATION AIR Install openings and ductwork to the boiler room providing fresh outside combustion and circulating air, as required by installation code CSA B139, NFPA31, NFPA211 and local codes. If the boiler is installed in a confined room and all air is taken from an adjacent, unconfined, indoor space, provide 2 openings of not less than 1 sq in. - Page 22 SET BURNER FOR EFFICIENT OPERATION BURNER SETTING Use burner settings in the table on page 25, or operating decal, as a guide to set the burner, particularly for nozzle changes. These settings are only starting points for the adjustments and are not meant as final settings.
- Page 23 All your tests must be done with the burner cover on COMBUSTION After 10 minutes of normal operation, take a smoke test and adjust SETTING/ the burner to obtain a reading of “1” on the smoke scale. EFFICIENCY To reach the maximum smoke test value, a 10 full slow steady pump action is required.
