The relief valve is set to open at 30 psi. If the valve is replaced, the replacement must have a relief capacity in excess of the DOE heating capacity for the boiler. Pipe the discharge of the relief valve to a location where water or steam will not create a hazard or cause property damage if the valve opens. The end of the discharge pipe must terminate in an unthreaded pipe. If the relief valve discharge is not piped to a drain, it must terminate at least 6 inches above the floor. Do not run re
Be careful to cut the pipe square. De burr the cut end with a file or emery cloth. d) Make an insertion mark 1” from the male end of the outer pipe. e) Cut the plastic inner pipe so that it will protrude 3/8” beyond the male end of the outer pipe when reinstalledin the outer pipe. Use a fine tooth hacksaw or a PVC saw to cut the plastic pipe and be careful to cut the pipe square. De burr the cut edge of the plastic pipe with a file, razor blade, or fine sandpaper. f) Reinstall the inner pipe. FI
Stainless vent manufacturer’s wall thimble part numbers are shown in Table 7.5. Note that concentric vent has a “zero” clearance to combustibles and therefore does not require the use of wall thimbles.

These options include: 1) 80/125mm concentric venting may be used to achieve longer vent runs. 2) 80/125mm concentric venting may be used for vertical vent applications. 3) An 80/125mm concentric snorkel kit is now offered. 4) Metal-Fab “Corr/Guard” may now be used for stainless steel vent applications.

2. Connect a speaker to each channel output using Speakon®, Banana Plugs, or bare wire. Factory Preset #2: BRIDGE Putting the amplifier in BRIDGE (bridge-mono) mode delivers the power of both amp channels into a single 8 or 4 ohm load. The XTi2 Series amplifiers come pre-loaded with a preset that makes it easy to configure the amplifier for this operation. Before you get started ensure that you: 1. Connect signal source to Channel 1 and Channel 2 using XLR connectors (the amplifier inputs will a

The temperature must be set below the lowest permissible temperature for any system related component affected by boiler supply water. Under no circumstances can the high limit aquastat be set higher than 250°F. I. BOILER MODULATING CONTROL - Various controls are used to modulate burner firing rates. No attempt will be made to cover every possibility, however a general outline will be given. Most modulation controls require the entry of a boiler temperature identifying boiler operation at the
