Page 6: Clearance To Combustibles
WARNING Clearance to combustibles Location of flammable or explosive objects, liquids or vapors close to the heater may cause fire or explosion and result in property damage, injury or death. Do not use, store or locate flamma- ble or explosive objects, liquids or vapors in proximity of the heater. The clearance to combustible material represents the minimum dis- tance that must be maintained between the outer heater surface and a nearby surface. -

Page 22: Flue Venting
WARNING 11. FLUE VENTING Inadequate venting of a heater may result in asphyxiation, carbon monoxide poisoning, injury or death. This heater may use a vent connection or indirect venting system to remove products of combustion from the space. Seal all vent connections with high temperature sealant. - Page 23 heaters must be controlled by a single common thermostat or “ON/OFF” switch. A minimum 10 inch (25 cm) length of minimum 26 gauge single walled 4” (10 cm) diameter vent pipe is to be installed on the swaged end of the last tube before any Tee or Elbow is fitted.
- Page 24 Use the approved 4" (10 cm) (JA-0528-XX) or 6" (15 cm) (JA-0529-XX) horizontal wall vent terminal or a high-wind termination cap approved by a recognized certification agency Install termination cap a minimum of 18 inches (45 cm) from the outside wall to the inside edge of terminal opening to alleviate back pressure caused by turbulent wind conditions (See Fig.

NOTE: Access to the manifold pressure test port is on the top of the valve. A 3/16" Allen Wrench is necessary to check this. When checking or setting the manifold pressure, a water manometer should be used. Gauges which measure in ounces per square inch or pounds per square inch are not accurate enough to properly measure or set the pressure. - Page 29 FIGURE 20 ORIENTATION OF FLEXIBLE GAS CONNECTOR The flexible gas connector MUST be installed in the orientation shown below as required by national installation codes and by the certification standard of this heater. This orientation protects the flexible gas connector from damage due to movement during heater expansion.

Page 33: Sequence Of Operation
20 SEQUENCE OF OPERATION The S87 ignition control module is powered by a 24v transformer and activated when the ther- mostat calls for heat. On every call for heat the S87J will delay start-up to provide a 30 second system pre-purge. When the S87 is activated by a thermostat or call for heat an internal trans- former provides power to the electronic generator circuit for Spark Ignition and the safety lock- out timing begins. -
