How to Install a Natural Gas Direct Vent Heater from Martin Direct

1. Choose the Installation Site

Select a location along the exterior wall of your house. The site should be free of obstructions and provide adequate airflow for the heater. Consider the position of doors and windows to ensure proper ventilation for your unit.

2. Mark and Cut the Opening

Measure and mark the area where the adjustable vent assembly will pass through the exterior wall. Cut an opening along those walls that fit the width and height of the vent. This allows the exhaust and combustion products to be directed outside, maintaining clean hot air inside the house. Make sure the gas flame will be sealed away from all contact with room air for clean and comfortable heat.

3. Install the Adjustable Vent Assembly

Place the vent assembly through the opening in the exterior wall. Ensure it adjusts to fit walls of different thicknesses. The adjustable vent assembly adjusts easily, allowing it to fill various wall lengths. Secure it with the hardware provided, making sure it’s level.

4. Connect the Gas Line

5. Secure the Heater Unit

6. Connect the Vent Assembly

Attach the vent assembly to the heater. Ensure a tight seal to prevent any leaks of combustion products into the room. The vent assembly adjusts to fit different wall lengths, ensuring a secure fit.

7. Install the Pilot Assembly

Follow the manufacturer’s instructions to install the pilot assembly. This is crucial for the operation of the gas flame. Ensure all connections are tight and secure.

8. Perform a Leak Test

Turn on the gas supply and check all connections for leaks using a soap and water solution. Bubbles indicate a leak, which must be addressed immediately.

9. Connect the Power Supply

If your heater model requires electricity, plug it into a suitable outlet. Ensure that the power supply is compatible with the heater’s requirements.

10. Start the Heater

Turn on the heater and set the desired temperature. Monitor the unit for the first few hours of operation to ensure it is functioning correctly and providing comfortable heat.
