Install flue pipe assembly (reference FIG. 2-2 for flue pipe assembly)

The outdoor boiler is shipped with all the necessary vent components. All components must be installed prior to operation. Basic installation steps are as follows:

1.	Locate all venting components from the installation kit
	and carton.
2.	Before connecting the flue pipe sections or components,
	verify the gasket is seated evenly inside the groove in the
	female end of the elbow and flue adapter.
3.	Remove the kit provided screws from the air cover and
	use them to install the wall strap.

￿WARNING

For a boiler already installed, you must turn off gas supply, turn off power and allow boiler to cool before proceeding. You must also completely test the boiler after conversion to verify performance as described under Start-up, Section 7 of this manual. Failure to comply could result in severe personal injury, death, or substantial property damage.

You must install a propane orifice to operate the outdoor boiler on propane gas. Verify when installing that the orifice size marking matches boiler size (Table 2A).

4. Insert the elbow into the flue adapter.
	Do not use grease or other lubricant
￿ CAUTION
	on the vent seals. Only water may be

used for this purpose. Grease or other lubricant can make the seal brittle or it can result in tears in the surface of the seal, this will result in flue gas leakage.

1.Remove the top and front access covers from the unit (tools required for removal).

2.Remove the three screws securing the gas valve to the venturi (FIG. 2-3).

3.Locate the propane orifice disk from the conversion kit bag. Verify that the stamping on the orifice disk matches the boiler size (see Table 2A).

Place the orifice into the black rubber grommet in the side of the gas valve and secure in the valve (FIG. 2-3).

4.Reposition the gas valve against the venturi and replace the screws (FIG. 2-3) securing the valve to the venturi.
