How to Install a Propane Wall Heater: A Comprehensive Guide

Installing a propane wall heater can be a straightforward process, but it’s essential to follow the manufacturer’s instructions and local building codes to ensure safety and proper operation. This comprehensive guide will walk you through the step-by-step process of installing a propane wall heater, providing detailed technical specifications and references to help you complete the project successfully.

Choosing the Location

The first step in installing a propane wall heater is to select a suitable location. This decision should be based on the manufacturer’s recommendations and local building codes. Consider the following factors when choosing the location:

Clearance Requirements: Ensure the heater is installed with the minimum clearances from combustible materials, as specified by the manufacturer. This typically ranges from 6 to 36 inches, depending on the model.
Ventilation: The heater should be placed in a well-ventilated area to ensure proper air circulation and prevent the buildup of carbon monoxide.
Accessibility: Choose a location that allows easy access for lighting the pilot light, adjusting the controls, and performing maintenance.
Proximity to Propane Tank: The heater should be installed as close as possible to the propane tank to minimize the length of the gas line.

Preparing the Wall

Before installing the heater, you’ll need to prepare the wall. Depending on the wall material, you may need to drill a hole to accommodate the gas line. Check local building codes for specific clearance requirements and any additional wall preparation needed.

Installing the Gas Line

The gas line for a propane wall heater is typically a 3/4″ black pipe or CSST (Corrugated Stainless Steel Tubing) that runs from the propane tank to the heater. Here’s how to install the gas line:

Run the Gas Line: Drill a hole through the wall, as close to the heater location as possible. Run the 3/4″ black pipe or CSST tubing through the hole, ensuring it is securely in place.
Connect to the Heater: Attach a flexible connector to the end of the gas line. The flexible connector should be 3/8″ in diameter and listed and approved for gas connections.
Secure the Connection: Tightly screw the flexible connector into the heater’s gas inlet, using plumbing tape to ensure a secure and leak-free connection.

If using CSST tubing, it’s essential to properly bond and ground the system to prevent potential electrical issues.

Connecting the Propane Tank

With the gas line installed, it’s time to connect the propane tank. Use a dual-tank connection kit to ensure a secure and leak-free connection. Apply orange thread tape or sealant to all threaded connections to prevent leaks.

Installing the Heater

Mount the propane wall heater on the wall using the provided bracket. Ensure the heater is level and securely fastened to the wall.

Connecting the Heater to the Gas Line

Remove the Gas Inlet Cap: Unscrew the cap from the heater’s gas inlet.
Attach the Threaded Fitting: Apply plumbing tape to a 3/8″ threaded fitting and screw it into the heater’s gas inlet until it is tight and secure.
Connect the Flexible Connector: Attach the flexible connector to the threaded fitting, ensuring a tight and secure connection.

Testing for Leaks

After connecting the heater to the gas line, it’s essential to check for any leaks. Use a soap and water solution and apply it to all connections. If bubbles appear, tighten the connection or check for any damage.

Lighting the Pilot Light

Follow the manufacturer’s instructions to light the pilot light and ensure the heater is functioning properly. This may involve adjusting the gas control valve, setting the thermostat, and verifying the flame is burning correctly.
