4 I. Pre-Installation C. Appliance is design certified for installation on combustible flooring. The boiler must not be installed on carpeting. D. Provide clearance between boiler jacket and combustible material in accordance with local fire ordinance.
5 2 . Determine Total Input of all appliances in space. Round result to nearest 1,000 Btu per hour (Btuh). 3 . Determine type of space. Divide Volume by Total Input. a . If result is greater than or equal to 50 ft³ per 1,000 Btuh, space is considered an unconfined space .
6 III. Water Piping and Trim CAUTION Failure to properly pipe boiler may result in improper operation and damage to boiler or building. A. Design and install boiler and system piping to prevent oxygen contamination of boiler water.
7 Figure 3: Recommended Boiler Piping For Series - Loop Hot Water Heating Systems Figure 4: Recommended Piping for Combination Heating & Cooling (Refrigeration) Systems.
8 IV. Gas Piping A. Size gas piping. Design system to provide adequate gas supply to boiler. Consider these factors: 1. Allowable pressure drop from point of delivery to boiler. Maximum allowable system pressure is ½ psig. Actual point of delivery pressure may be less; contact gas supplier for additional information.

10 Table 5: Burnham Vent System Components Figure 7: Vent Connector Installation B. Removal of Existing Boiler. For installations not involving the replacement of an existing boiler, proceed to Step C.
11 D. Install Vent Pipe, General. 1. Start at vent connector. Work toward vent terminal. 2. Use ¾ inch pipe strap to support horizontal runs, maintain vent location and slope, and prevent sags. Do not restrict thermal expansion movement. Maximum support spacing is 5 feet.
12 Figure 9: Recommendations for Thimble and Wall Penetration VI. Electrical A. General. Install wiring and ground boiler in accordance with requirements of authority having jurisdiction, or in absence of such requirements the National Electrical Code , ANSI/NFPA 70, and/or the CSA C22.
13 Figure 10: Wiring Diagram Figure 11: Main Burner Installation VII. System Start-up A. Safe operation and other performance criteria were met with gas manifold and control assembly provided on boiler when boiler underwent tests specified in American National Standard for Gas-Fired Low- Pressure Steam and Hot Water Boilers, ANSI Z21.
14 Figure 12: Gas Valve Pressure Tap D. Prepare to check operation. 1. Obtain gas heating value (in Btu per cubic foot) from gas supplier. 2. Connect manometer to pressure tap on gas valve. See Figure 12. 3. For natural gas fired boiler, temporarily turn off all other gas-fired appliances.
15 Figure 16: Main Burner Flame J. Check thermostat operation. Raise and lower temperature setting to start and stop boiler operation. K. Check ignition control module shut-off. Disconnect igniter/sensor cable from Terminal 9 (SPARK). Gas valve should close and pilot and main burners should extinguish.
16 Figure 17: Operating Instructions Adjust gas valve pressure regulator as necessary (turn adjustment screw counterclockwise to decrease manifold pressure, or clockwise to increase manifold pressure). If pressure can not be attained, check gas valve inlet pressure.
17 TROUBLE SHOOTING GUIDE SPLIT (SEPARATE) CONTROLS, 24 VOLT OPERATION WITH ELECTRONIC IGNITION AND INTERMITTENT CIRCULATION NOTE: 1. Read Sequence of Operation prior to using Trouble Shooting Guide. See Page 14. 2. Prior to replacing a control, always check for broken wires or loose connectors that provide power to that control.

19 Note : Minimum pilot signal should be 1.0 microamps. Disconnect Pilot Ground wire from Module and connect DC microammeter between Ground Terminal and Pilot Ground wire.
20 Important Product Safety Information Refractory Ceramic Fiber Product Warning : This product contains refractory ceramic fibers (RCF). RCF has been classified as a possible human carcinogen. After this product is fired, RCF may, when exposed to extremely high temperature (>1800F), change into a known human carcinogen.
21 VIII. Service A. General. Inspection and service should be conducted annually. Turn off electrical power and gas supply while conducting service or maintenance. Follow instructions TO TURN OFF GAS TO APPLIANCE. See Figure 17. CAUTION Label all wires prior to disconnection when servicing controls.
22 Table 7: Pilot Burner Location Figure 18: Spark Gap Setting Figure 19: Flueway Cleaning at rear of burner. See Figure 11. Slide burner over orifice. 7. Reconnect pilot gas supply, igniter/sensor cable, and ground wire. Reinstall Burner Access Panel.
23 Table 8: Minimum Suction Pressure Figure 20: Procedure for Measuring Fan Suction Pressure I. Lubrication. There are no parts requiring lubrication by service technician or owner. Circulator bearings are water lubricated. Blower motor bearings are factory sealed.
