7 GENERAL SAFETY T o meet commercial hot water use needs, the high limit safety control on this water heater will shut off the main gas valve before the outlet temperature reaches 210°F . However , water temperature s over 125°F can cause instant severe burns or death from scalds.
Equipment Base The heater should be mounted on a level, structurally s ound surface. The heater is approved for installation on a combustible surface but must NEVER be i nstalled on carpeting. Gas-fueled equipment installed in enclosed parking garages must be located at least 18 in.
9 Fig. 6: Minimum Clearances from Combustible Surfaces – Indoor and Outdoor Installations l ation codes and the requirements of the gas supplier . Three sides must be open in the area under the over- hang. Roof water drainage must be diverted away from heaters installed under overhangs.

11 Air Filter An air filter is supplied standard with the heater . This filter is shipped loose for field installation. Refer to the Air Filter Kit Installation Instructions (Part No. 241338) for details. Direct V ent If outside air is drawn through the intake pipe directly to the unit for combustion: 1.
shall communicate directly , or by ducts, with the o utdoors or spaces (crawl or attic) that freely com- municate with the outdoors. a. Where directly communicating with the out- doors or where communicating to the outdoors through vertical ducts, each open- ing shall have a minimum free area of 1 in.
R elief V alve Piping T emperature & Pr essur e Gauge The temperature and pressure gauge is shipped loose for field installation and must be installed within 12 inches of the boiler outlet (if possible) in an easily readable location. Installation must comply with ASME Section IV as well as all applicable national, state and local codes.
14 longer than 7 minutes or where cold water operation is continuous, provisions must be made to mix higher t emperature outlet water with the colder inlet water and thereby raise the inlet temperature to at least 120°F (49°C) within the 7-minute time limit.

16 T hr ee-Way V alv es Three-way valves intended to regulate system water temperatures by reducing flow in the boiler should not be used. Raypak heaters are high-recovery , low-mass h eaters which are not subject to thermal shock. See Fig. 16 and instructions on page 17 for adjusting the manual bypass.
17 The MVB must be equipped with a field-supplied ex- te r n a l pu m p an d by p a ss a rr a n g e m e nt . T h i s arrangement blends outlet water with the inlet water to i ncrease the inlet water temperature to a minimum of 120°F (49°C), thereby reducing the likelihood of con- d ensation forming on the heat exchanger .
18 P ool/Spa Water Chemistr y Chemical imbalance can cause severe damage to the pool heater and associated equipment. Maintain the water chemistry according to the chart below .
19 Further advice should be obtained from your pool or spa builder , accredited pool shop, or chemical suppli- er for the correct levels for your water . Automa tic Chlorinator s and Chemical F eeder s All chemicals must be introduced and completely dilut- ed into the pool or spa water before being circulated through the heater .
20 • Safety wiring must be NEC Class 1. • Heater must be electrically grounded as required by the NEC. • In Canada, CSA C22. 1 C.E.C. Part 1. The MVB 503-1503 heaters are wired for 120 V AC, 12 amps while the MVB 1753 & 2003 heaters are wired for 120 V AC, 18 amps.
C heck the power source: AC = 108 V AC Minimum, 132 V AC MAX AB = 108 V AC Minimum, 132 V AC MAX BC = <1 V AC Maximum Making the Electrical Connections Refer to Fig. 18-21. 1. V erify that circuit breaker is properly sized by referring to heater rating plate.
22 Field W iring Connection V enting General Appliance Categories Heaters are divided into four categories based on the pressure produced in the exhaust and the likelihood of condensate production in the vent.

26 C ommon V enting T he NFGC does not address sizing guidelines for the common venting of multiple Category IV heaters. This is covered in the NFGC under “Engineered V ent Sys- tems”.
27 Fig. 25: Horizontal Through-the-W all V enting Fig. 26: Alt. Horizontal Through-the-Wall V enting NO TE: While a drain connection is required in the vent of all MVB installations, the drain can be ac- complished in several different ways.
28 The vent must be installed to prevent flue gas leakage. Care must be taken during assembly to ensure that all joints are sealed properly and are airtight. The vent must be installed to prevent the potential accumulation of condensate in the vent pipes.
29 The total length of air supply pipe cannot exceed the distances listed in T ables L and N. Each elbow used is e qual to 10 ft of straight pipe. This will allow installation in any arrangement that does not exceed the lengths shown in T ables L and N.
F r eeze Protection The Raypak electronic temperature control includes a freeze protection feature. In the event the temperature drops below 40°F at any of the boiler temperature sen- sors, the pump is turned on and will remain on until the temperature at all boiler sensors rises to 45°F .
31 Mode 3 – Dedicated DHW operation using UniT emp 80 piping. A call for heat is determined by the DHW sensor and the DHW boiler target. The heater outlet water is also controlled to the boiler target tempera- ture. See Fig. 32. Mode 4 (Not supported) – Outdoor reset using pri- mary piping.
32 MODULA TING * Fig. 34: Mode 7 Primary/Secondary Piping with External T arget T emp *Maximum 4 times the pipe diameter or 12”, whichever is less. Mode 8 – This mode is for remote firing control of the heater via an external sequencer such as the Raypak T empT racker MOD+.
