Lennox Hearth E36ODGPE-H New York and Massachusetts requirements, General Information, All Models

New York and Massachusetts requirements

These appliances may be installed in the following USA locations with the following requirements:

Installation of these appliances are approved for installation in the US state of Massachu- setts if the following additional requirements are met -

•Installation and repair must be done by a plumber or gas fitter licensed in the Common- wealth of Massachusetts.

•The flexible gas line connectors shall not exceed 36 inches (92 centimeters) in length.

•The individual manual shut-off must be a t-handle type valve.

General Information

Note: Installation and repair should be per- formed by a qualified service person. The appli- ance should be inspected annually by a qualified professional service technician. More frequent inspections and cleanings may be required due to yard care, insects, etc. It is imperative that the control compartment and burners of the appliance be kept clean.

Provide adequate clearances around air open- ings and adequate accessibility clearance for service and proper operation. Never obstruct the front openings of the appliance.

These appliances are designed to operate on natural or propane gas only.

All Models -

All models have a manually modulated gas valve. Input is shown in Table 1:

Gas Pressure - All Models

Tables 2 and 3 show the appliances' inlet and manifold gas pressure.

Inlet Gas Supply Pressure

(all models)

Fuel #	Minimum	Maximum
Natural Gas	5.0" WC	10.5" WC
	(1.24 kPa)	(2.61 kPa)
Propane	11.0" WC	13.0" WC
	(2.74 kPa)	(3.23 kPa)

Manifold Gas Supply Pressure

(all models)

Fuel #	Low	High
Natural Gas	(Lo) 2.2" WC	(Hi) 3.5" WC
	(.55 kPa)	(.87 kPa)
Propane	(Lo) 6.3" WC	(Hi) 10.0" WC
	(1.57 kPa)	(2.49 kPa)

Table 3

Test gage connections are provided on the front of the gas control valve identified IN for the inlet and OUT for the manifold side. A 1/8" NPT Test gauge connection is provided at the inlet and outlet side of the electronic gas control valve.

These appliances must be isolated from the gas supply piping system (by closing their individual manual shut-off valve) during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).

These appliances and their individual shut-off valves must be disconnected from the gas sup- ply piping system during any pressure testing of that system at pressures greater than 1/2 psig (3.5 kPa).

Orifice Sizes - Sea Level To High Altitude (All Models)

These appliances are tested and approved for installation at elevations of 0-4500 feet (0-1372 meters) above sea level, using the standard burner orifice (See Table 4 ). For elevations above 4500 feet, contact your gas supplier or qualified service technician. Install the appli- ance according to the regulations of the local authorities having jurisdiction and, in the USA, the National Fuel Gas Code NFPA 54 / ANSI Z223.1 - latest edition or , in Canada, the CAN1- B149.1 and .2 codes - latest edition.

Model	Orifice size		Elevation
	Natural		Feet
No.		Propane
	Gas		(meters)
E36OdG	0.1405"	0.0785"
	(#28)	(#47)	0-4500
E42OdG	0.1405"	0.0785"	(0-1372)
	(#28)	(#47)

Warning: Propane tanks are at pressures that will cause dam- age to valve components. Verify that the tanks have step down regulators to reduce the pres- sure to safe levels.
