10-A SUGGESTED SEISMIC RESTRAINT - Lateral and Longitudinal Planes NOTE: Seismic restraint requirements vary greatly by geographic region or area. The information below is a guideline only for suspension of the heater. Adhere to specific seismic requirements and specifications of local engineering authority. In areas prone to earthquake, or specified on a project, install lateral and longitudinal seismic restraints as suggested in Figure 7.
WARNING 11. FLUE VENTING Inadequate venting of a heater may result in asphyxiation, carbon monoxide poisoning, injury or death. This heater must be connected to a vent to remove products of combustion from the space. Seal all vent connections with high temperature sealant. Venting must be in accordance with all local, state, provincial, and national codes (ANSI Z223.1/NFPA 54 in USA) and as indicated below in this manual. This heater must be vented directly to the outside.
FIGURE 9 - Horizontal Vent - ALL vent pipe and adapters are field supplied Using Horizontal Vent Terminal 902000002 A wall thimble is not required through a noncombustible wall. Seal pipe penetration. 902000002 (Optional) Seal all vent connections with high temperature sealant. FIGURE 10 - Horizontal Vent Offset Allow free expansion and contraction of the system, and free flow of vent gas.
Horizontal vent through a side wall: (Vertical vent through roof is on page 23) • Refer to General Venting Requirements on page 19 • Seal all vent connections with high temperature sealant. • Minimum length of a horizontal side-wall vent: • Regardless if a 90° elbow is installed, a Minimum linear 36 inch (3 ft; 91 cm) single wall ‘C’ vent plus minimum 12 inch (30.

Vertical vent through the roof: (Horizontal vent through side wall is on pages 20 21) It is the sole responsibility of the installer to adhere to all current local codes and/or ANSI Z223.1 latest editions for all venting requirements, and practices. • Refer to General Venting Requirements on page 19 • Seal all vent connections with high temperature sealant.
12 COMBUSTION AIR REQUIREMENTS Outside combustion air must not be ducted directly to this appliance. Do not install a filter at the combustion air inlet. Make provision to ensure adequate combustion and ventilation air in the space: • USA: In accordance with Section 9.3 ANSI Z223.1 / NFPA-54 for a fan-assisted appliance. Ensure adequate clearance around the air intake (at top of burner cabinet) to allow sufficient combustion air supply to the heater.
13. GAS SUPPLY - GAS CONNECTION … continued Provide a 1/8 in (3.2 mm) NPT plugged tapping, accessible for test gauge connection, immediately upstream of the gas supply connection to the heater. The gas supply should be checked first with heater turned “OFF” followed by another check with heater turned “ON”. This appliance and its main gas valve must be disconnected from the gas supply piping system during any pressure testing of the gas supply piping system at test pressure in excess of 1/2 psi (3.5 kPa).
REQUIRED ORIENTATION OF FLEXIBLE GAS CONNECTOR It is the responsibility of the installer to ensure correct gas connection. Confirm local requirements for gas connection with local authority. Where allowed or required by local code, a flexible gas connector may be used. Refer and adhere to local code requirements and NFPA 54 Section 9.6 (in the USA).
14. GAS CONVERSION WARNING: Gas conversion must only be performed by a trained gas service technician. Do not convert heater to alternate gas without using the proper kit listed below. Property damage, injury or death could result. Standard production of this model heater is for use with natural gas.
18. RECOMMENDED MAINTENANCE Improper adjustment, alteration, service or maintenance can cause property damage, injury or death. This heater must be installed and serviced only by a trained gas service technician. At least annually inspect the entire heater system, venting, and gas supply connections prior to the heating season. Replace worn parts and repair deficiencies. 1. Periodically check the inlet air opening and the blower squirrel cage vanes, cleaning off any lint or foreign matter.
19. FENWAL DSI WIRING DIAGRAM: (FENWAL S87J - PAGE 30; CHANNEL MICRO 50N - PAGE 31) 24V OR 120 VOLT THERMOSTAT - SINGLE HEATER PER THERMOSTAT NOTE: Heater must be controlled by 24Vac Thermostat to enable post-purge by the ignition control. Line voltage control disables the post-purge feature.
P/N: 905000020 20.
21. FENWAL DSI: SEQUENCE OF OPERATION / FLAME RECOVERY / SAFETY LOCKOUT Power Up / Stand By Upon applying 24 volts power to 24VAC, the control will reset, perform a self check routine, initiate full time flame sensing, flash the diagnostic LED for up to four seconds, and enter the thermostat scan state. Heat Mode When a call for heat is received from the thermostat supplying 24 volts to TH, the control checks the pressure switch for normally open contacts.
Flame Fault If at any time the main valve fails to close completely and maintains a flame, the full time flame sense circuit will detect it and energize the combustion blower. Should the main valve later close completely removing the flame signal, the combustion blower will power off following the optional post purge period. Fault Conditions The LED will flash on for 1/4 second, then off for 1/4 second during a fault condition. The pause between fault codes is 3 seconds.
SERVICE CHECKS Multipurpose Meter Flame current passes through the flame from the sensor to ground. The minimum flame current necessary to keep the system from lockout is 0.7 microamps. To measure flame current, connect an analog DC microammeter to the FC- FC+ terminals per figure at right. Use Microamp scale FC- FC+ Meter should read 0.7 µA or higher. If the meter reads below “0” on analog scale, meter leads are reversed. Disconnect power and reconnect meter leads for proper polarity.
