Overview

The provided document is an installation and operation manual for a Suburban Direct Vent Gas Water Heater with Direct Spark Ignition (DSI), designed specifically for recreational vehicles (RVs) and mobile housing.

Function Description

This device is a gas-fired water heater that uses a direct vent system to provide hot water. It incorporates Direct Spark Ignition (DSI) for automatic burner lighting, eliminating the need for a pilot light. The water heater is designed to maintain a water temperature of approximately 130°F (54°C) and includes a high-temperature limit (ECO) as a safety cut-off device, which trips if the water temperature exceeds 180°F. Some models also include an electric heating element for an alternative heating source. The direct vent design ensures that all air for combustion is supplied from outside the structure, and flue products are vented externally, preventing their entry into occupied spaces.

Important Technical Specifications

  • Models Covered: SW10D, SW10DM, SW10DE, SW10DEM, SW12D, SW12DE, SW12DEM, SW16D, SW16DE, and 16DEM. The "DE" and "DEM" suffixes indicate models with an electric element.
  • Ignition System: Direct Spark Ignition (DSI) for automatic burner lighting.
  • Temperature Control: Non-adjustable thermostat set to maintain 130°F (54°C).
  • Safety Cut-off: High-temperature limit (ECO) trips at 180°F (82°C) for both gas and electric elements (on applicable models).
  • Electrical Connections (Gas Models): 12 Volts D.C. (18 GA., 105°C wire or equivalent).
  • Electrical Connections (Electric Element Models): 120 Volts A.C., single phase, 1440 Watt element, 60 Hz, 12 Amps (14 GA., 105°C wire or equivalent).
  • Gas Connection: 3/8" gas supply line to a 3/8" flare fitting at the gas valve.
  • Water Connections: 1/2" female pipe fittings at the rear of the tank, marked "HOT" and "COLD," each containing a plastic fill tube to enhance water circulation.
  • Clearances: Minimum clearance from combustible construction on sides, top, floor, and rear is 0 inches.
  • Pressure Relief Valve: Designed to open if water temperature reaches 210°F or water pressure reaches 150 PSI.
  • Anode Rod: Magnesium or aluminum anode rod for tank protection.
  • Altitude Operation: Approved for use without modification up to 4500 feet. Above this altitude, a 4% reduction in thermal capacity per 1000 feet is recommended.

Usage Features

  • Automatic Operation: The DSI system automatically lights the burner, eliminating manual pilot lighting.
  • Dual Fuel Capability (on "DE" and "DEM" models): Offers the flexibility of using either gas or an electric element for heating water.
  • Safety Warnings: Emphasizes critical safety procedures, including filling the tank with water before operation, checking for gas leaks, and precautions regarding hydrogen gas accumulation after periods of non-use.
  • Freeze Protection: Instructions are provided to drain the heater if it will be subjected to freezing temperatures to prevent damage.
  • Odor Control: Addresses "sulfur water" odor issues and provides a chlorination procedure for the water system.
  • Easy Installation: Detailed instructions for flush mounting the unit, including framing requirements and securing the control housing and door frame.
  • Module Board: The module board, which controls the DSI system, is designed to be permanently mounted by the installer in an accessible location, protected from moisture and chemicals.

Maintenance Features

  • Anode Rod Protection: The tank is protected by a magnesium or aluminum anode rod, which should be inspected and replaced yearly (or more frequently with high iron/sulfate water) to prolong tank life and maintain warranty.
  • Burner Inspection: Regular inspection for yellow or erratic flames and soot accumulation is recommended, as these indicate incomplete combustion and an unsafe operating condition.
  • Vent Inspection: Periodic inspection of the vent for obstructions or soot is crucial for safe operation.
  • Grommet Seal Check: Frequent checks of the gas inlet grommet are advised to ensure an airtight seal, preventing flue products from entering the living area.
  • Wiring Inspection: Periodic inspection of wiring and connections for damage, fraying, and tightness is recommended.
  • Draining and Storage: Comprehensive instructions for draining the water heater for winterization or extended storage, including the removal of the anode rod if antifreeze is used in the plumbing system.
  • Troubleshooting: Provides a basic checklist for common issues like the burner not lighting (e.g., switch off, gas supply empty, ECO tripped).
  • No User Adjustments: The thermostat is not adjustable, and users are warned against altering the operation or design of the water heater. Repairs should only be performed by qualified service personnel using factory-authorized parts.
