required Wiring connections for the relay modules are unique refer to Fig 2 3 4 or the correct for proper subbase wiring and charts Wiring must comply with all applicable codes and regulations Wiring must comply with NEC Class 1 Line Voltage Loads connected to the RM7800 RM7840 must not those listed on the RM7800 RM7840 label or Specifications see Table 1 Limits and interlocks must be rated to simultaneously and break current to the ignition transformer valve and main fuel valve s All external timers must be listed or component by authorities who have jurisdiction for specific purpose for which they are used For on off gas fired systems some authorities who jurisdiction prohibit the wiring of any limit or contacts in series between the flame control and the main fuel valve s Two Flame Detectors can be connected in parallel the exception of Infrared Flame Detectors This equipment generates uses and can radiate frequency energy and if not installed and used accordance with the instructions may cause to radio communications It has been and found to comply with the limits for a B computing device of Part 15 of FCC rules are designed to provide reasonable protection such interference when operated in a environment Operation of this in a residential area may cause in which case the users at their own may be required to take whatever are required to correct this interference digital apparatus does not exceed the Class B for radio noise for digital apparatus set out in Radio Interference Regulations of the Canadian of Communications not install the relay module where it could be subjected to in excess of 0.5G continuous maximum vibration relay module is not designed to be weather tight installed outdoors protect the relay module using an weather tight enclosure Wiring Subbase Mount the subbase in any position except horizontally the bifurcated contacts pointing down The vertical position is recommended Any other decreases the maximum ambient temperature Select a location on a wall burner or electrical panel Q7800 can be mounted directly in the control Be sure to allow adequate clearance for installation access or removal of the Expanded
