1 I Pr oduct Description The ODV series boiler is a cast iron oil red boiler designed for use in forced hot water heating systems. The ODV boiler must be vented using the factory supplied venting system with combus - tion air taken from outdoors. The ODV uses the same three pass “scotch marine” heat exchanger as the CT series boiler .
2 IISpecications Ratings based on #2 fuel oil having a higher heating value of 140,000 BTU/Gal Net ratings based on a piping and pickup loss allowance of 1.15 Exhaust pipe: 4” I.D. insulated exible vent pipe. Maximum exhaust pipe length – 15 ft.
3 IIIBefor eInstalling 1) Safe, reliable operation of this boiler depends upon installation by a professional heating contractor in strict accordance with this manual and the authority having jurisdiction.
4 V V entSystemInstallation The ODV boiler is shipped with a complete venting system consisting of the following components: • FDVS-4 direct vent terminal • Backing plate • 15-ft length.
5.
6 g) Do not locate terminal under decks. h) It is preferable to install the terminal on the wall that is away from the prevailing wind. i) Do not put terminal under a soft or other overhang deeper than 18 inches. T op edge of terminal must be at least 2 ft below soft or overhang (Fig 3).
7.
8 3) INST ALLA TION OF THE VENT TERMINAL COMBUSTION AIR TEE (Figure 5c) a) Assemble the combustion air tee assembly body to the vent terminal outer pipe, and rotate to the desired position. Attach the tee assembly body to the vent terminal outer pipe with at least 3 sheet metal screws evenly spaced apart (not included).
9 NOTE: The tee may be rotated into any position so that the collar is in a convenient orientation. 4) APPLIANCE ADAPTER INST ALLA TION a) Apply a bead of red silicone sealant (supplied) to the boiler vent collar approx.
10 d) W ith a twisting motion, assemble the reducing tee adapter onto the boiler vent collar . e) Push the adapter onto the vent collar , using care to avoid damaging the appliance collar or the adapter (Figure 8b).
11 CAUTION • Do not enclose vent pipe in walls or ceilings • If necessary , the vent pipe may be cut to length with a hacksaw or cut off saw . Use safety glasses and other appropriate safety gear when cutting. • Make sure that the vent pipe route is nalized and pipe is accurately marked before cutting.
12 g) Push the inner vent pipe onto the termination inner pipe or appliance adapter all the way up to the stop bead. h) T ighten the inner pipe clamp bolts until both clamp halves are within 1/8” of each other at each end (Figure 9c).
13 VISystemPiping S tandardPiping Figure 17 shows typical boiler system connections on a single zone system. Additional information on hydronic system design may be found in Installation of Residential Hydronic Systems (Pub. #200) published by the Hydronics Institute in Berkely Heights NJ.
14 4) Fill V alve (Required) – Either a manual or automatic ll valve may be used. The ideal location for the ll is at the expansion tank. 5) Automatic Air V ent (Required) – At least one automatic air vent is required. Manual vents will usually be required in other parts of the system to remove air during initial ll.
15 PipingforSpecialSituations Certain types of heating systems have additional requirements. Some of the more common variations follow: 1) Indirect W ater Heaters – Figure 18 shows typical indirect water heater piping. Boiler piping is the same as for any two-zone system.
16 4) Systems containing oxygen – Many hydronic systems contain enough dissolved oxygen to cause severe corrosion damage to a cast iron boiler such as the ODV . Some examples include: • Radiant systems that employ tubing without an oxygen barrier .
17 VIIFuelPiping T wo basic piping systems are used to connect the boiler to the oil supply: 1) One-Pipe – Recommended where the fuel pump is below the lowest possible level of the oil in the tank. Basic piping is shown in Figure 21a. 2) T wo-Pipe – Recommended where the fuel pump is above the lowest possible level of the oil in the tank.
2) Do not use compression ttings in oil piping. 3) Do not use T eon tape in oil piping 4) Do not manifold multiple oil appliances on a two-pipe system. Run dedicated lines for each appliance back to the tank or use a transfer pump and day tank to get oil to a location where it can be gravity fed to each appliance.
19 19 IXStart-upandCheckout Use the following procedure for initial start-up of the boiler: 1) Make sure that the boiler and system are lled with water . 2) Check all system and fuel piping for leaks. Repair any leaks found immediately . 3) V ent system must be complete and free of obstructions before attempting to re boiler .
20 6) Start the boiler . Immediately take a smoke. If any smoke is present, open the air adjustment to obtain a zero smoke. 7) Allow boiler to warm up for about 15 minutes or until the binder has completely burned out of the combustion chamber . Adjust the air to obtain a CO2 between 1 1.
21 2) If a zero smoke cannot be obtained at a CO2 between 1 1.0 and 12.5%, check the following: a) Check nozzle and settings against those shown in T able 2 below . Nozzle must be identical to that called for in T able 2 including manufacturer . Check the burner manufacturer ’ s manual for dimensional settings not shown in this manual (e.
22 XIMaintenance Steps 1 – 10 below should be performed on an annual basis to assure reliable operation of the ODV boiler . If the boiler is used to power an indirect water heater , such as a Mega-Stor , it is advisable to check the CO2 and smoke level approximately half way between annual cleanings.
