Desa VTDMV24NA Placement of Loose Embers, Test Pressures Equal To or Less Than 1/2 Psig 3.5 kPa

INSTALLATION

Continued

6.Reconnect heater and equipment shutoff valve to gas supply. Check reconnected fit- tings for leaks.

Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)

1.Close equipment shutoff valve (see Figure 8).

2.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas or using compressed air.

3.Check all joints from gas meter to equipment shutoff valve for natural gas or propane/LPsupply to equipment shutoff valve for propane/LP (see Figure 9 or 10).Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

Pressure Testing Appliance Gas Connections

1.Open equipment shutoff valve (see Figure 8).

2.Open main gas valve located on or near gas meter for natural gas or open propane/LP supply tank valve.

3.Make sure control knob of appliance is in the OFF position.

4.Check all joints from equipment shutoff valve to gas control (see Figure 9 or 10). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Light appliance (see Operating Appliance, page 10) Check all other internal joints for leaks.

7.Turn off appliance.

PLACEMENT OF LOOSE EMBERS

4.	Correct all leaks at once.			CAUTION: Do not place
	Equipment	Open
			any loose embers around pilot
	Shutoff
			assembly.
	Valve
		Closed	Two bags of loose embers are provided with this
	Figure 8 - Equipment Shutoff Valve		unit. For this installation use the embers that are
			approximately 1" square in size. If needed, larger
Propane/LP		Equipment	embers can be broken to size. These embers aid
Supply Tank		Shutoff Valve	in concealing the burner pan, directing flames
			through the ember bed, quiet operation of the unit
			and gives a natural random flame pattern.
			Place embers as follows:
			1.	Place embers around the center ember bed or
				ember pod.
			2.	Place individual embers on their edge (not flat)
				along the top of the burner pan. This aids in
		Control Valve		directing flames from the burner through the
		Location		ember bed.
	Figure 9 - Checking Gas Joints			Note: Too many embers or embers placed flat
	(Propane/LP Gas Only)			along burner pan can suppress the flames.

3.When unit is lit, check flames for random appear- ance and ember bed glowing red-orange in color (see Burner Flame Pattern, page 11). If this is not happening, either add, remove or reposition loose embers. IMPORTANT: Turn unit off and let cool before repositioning loose embers.
