Operate relief valve To avoid water damage or scalding due to valve operation, a metal discharge line must be connected to relief valve outlet and run to a safe place of disposal. This discharge line must be installed by a qualified heating installer or service technician in accordance with the instructions in the AHE Series 4 Boiler Manual. The discharge line must be terminated so as to eliminate possibility of severe burns should the valve discharge. 1. Before proceeding, verify that the relief valve outlet has been piped to a safe place of discharge, avoiding any possibility of scalding from hot water. 2. Read the boiler pressure/temperature gauge to make sure the system is pressurized. 3. Lift the relief valve top lever slightly, allowing water to relieve through the valve and discharge piping. 4. If water flows freely, release the lever and allow the valve to seat. Watch the end of the relief valve discharge pipe to ensure that the valve does not weep after the line has had time to drain. If the valve weeps, lift the seat again to attempt to clean the valve seat. If the valve continues to weep afterwards, contact your qualified service technician to inspect the valve and system. 5. If water does not flow from the valve when you lift the lever completely, the valve or discharge line may be blocked.

In some instances, the odorant can fade and the gas may no longer have an odor. • Propane gas can accumulate at floor level. Smell near the floor for the gas odorant or any unusual odor. If you suspect a leak, do not attempt to light the pilot. • Use caution when attempting to light the propane pilot. This should be done by a qualified service technician, particularly if pilot outages are common. • Periodically check the odorant level of your gas. • Inspect boiler and system at least yearly to make sure all gas piping is leak-tight. • Consult your propane supplier regarding installation of a gas leak detector. There are some products on the market intended for this purpose. Your supplier may be able to suggest an appropriate device.
