Check all connections within the control cabinet. A loose connection could cause intermittent shutdowns. 9. Some burners will use direct spark ignition. They may use a single gas pressure regulator and gas valve or multiple valves and regulators.
- Page 14 EPV SERIES CONDENSING WATER BOILER This section is for two-stage firing only: After adjusting the high fire manifold gas pressure, it is now important to check the operation of the first stage (low fire). There is a toggle switch on the control cabinet labeled “Auto/Low Fire”. Switch from the auto position to low fire and the main valve will de-energize shutting off the high fire gas supply and the air damper will close reducing the airflow to a minimum.

The makeup of the water, just as the blowdown, will vary with each application. Rely on the recommendation of the water consultant. SINCE RIVERSIDE HYDRONICS CANNOT CONTROL THE USE OF THE BOILER, WATER CONDITIONS OR MAINTENANCE, THE WARRANTY ON THE BOILER DOES NOT COVER POOR PERFORMANCE, STRUCTURAL FAILURE OR LEAKING DUE TO AN EXCESSIVE ACCUMULATION OF SCALE. - Page 17 EPV SERIES CONDENSING WATER BOILER MAINTENANCE (con't) The need to periodically check water level controls and waterside of the pressure vessel cannot be over emphasized. Most instances of major boiler damage are the result of operating with low water or the use of untreated (or incorrectly treated) water.
