Dayton® Patio Heaters
To connect the gas:
!WARNING
Failure to install, operate or service this appliance in the approved manner may result in property damage, injury or death. This heater must be installed
and serviced by trained gas installations and service personnel only.
The installation of this heater must conform with local building codes or, in the absence of such codes, the National Fuel Code (NFPA 54).
The gas outlet must be in the same room as the appliance and accessible. It may not be concealed within or run through any wall, floor or partition.
1. Install a sediment trap / drip leg if condensation may occur at any point of the gas supply line. This will decrease the possibly of loose scale or dirt in the supply line entering the heater’s control system and causing a malfunction. NOTE: High pressure gas above 14 in. W.C.P. (water column pressure) requires a high pressure regulator and ball valve (field supplied).
2. A stainless steel flexible hose (field supplied) formed into a smooth
3. Attach the ball valve (field supplied) to the gas supply pipe. Apply pipe compound to NPT adapter threads to seal the joint. Use only a pipe compound resistant to liquid petroleum.
Note: Provide a 1/8 in. NPT plugged tapping accessible for test gauge connection immediately upstream of gas connection to the heater (provided on ball valve, when supplied).
4. Attach the gas connector (field supplied) to the adapter and the heater’s gas inlet. Seal the joints.
Important! The fittings (nuts) on the flexible connector (field supplied) must be connected to an adapter. They may not be directly connected to the gas supply pipe.
Excessive torque on the manifold may misalign the orifice. Always use two wrenches to tighten mating pipe connections.
5. Final assembly must be tested for gas leaks according to NFPA or local codes.
!WARNING
Testing for gas leaks with an open flame or other sources of ignition may lead to a fire or explosion and cause serious injury or death. Test in accordance with NFPA or local codes.
To disconnect the gas:
1. Disconnect the power to the heater.
2. Turn off the gas supply to the heater and “bleed” the gas line.
3. Using two wrenches, slowly loosen the fittings. Excessive torque on the manifold may misalign the orifice.
4. Inspect the hose and fittings for abrasion, wear or damage. Replace if necessary.
