the following steps:

  • Obtain the duct’s measurements. the duct’s length and diameter. Ensure that the heater’s flange and the duct’s diameter match. Measure the distance from the heater to the roof.
  • Determine the location of the heater duct vent hole on the roof.
  • Drill the roof hole that has been noted. Check to see if the duct can fit through the opening. Additionally, a hole must be made in the roof flashing underneath the shingles.
  • As heat protection, add a roof jack.
  • Insert the duct once you’ve made the holes.
  • The vent cap should be placed over the duct’s exterior end. To stop heat loss, fill in the cracks around the vent.

The same procedures that you use for venting vertically also apply to this technique. The distinction is in where the vent hole is placed; when venting horizontally, the hole will be on the wall rather than the roof.

You can place a wall thimble around the vent hole to shield the wall from the duct’s high temperature.

You can ask a specialist to examine the vent installation and provide you advice if it needs to be corrected.

What Advantages Do Heater Vents Offer?

Vents are necessary for proper air circulation around hearth appliances and heaters in enclosed spaces. Gas, oil, wood, or pellets are all acceptable fuel sources for the heater. Ventilation aids in clearing indoor spaces of dangerous gases and other combustion byproducts.

The following are additional advantages of creating a vent for your heater:

  • Improved temperature regulation
  • Energy-efficiency
  • Optimal heater performance
  • Enhances circulation and air quality
  • Removes a room’s draught

Venting has some drawbacks, including installation costs and its limited ability to reduce humidity. However, heating systems are always being improved to include humidity management. However, the heater’s more sophisticated functions come at a premium cost.

Vents are still worthwhile because they provide comfort and cost savings. To get the most out of adding a vent, pick a direction that works for you.

Which Vent Direction—Horizontal Or Vertical—Is Preferable?

The vent direction must be chosen carefully. Some considerations for the best decisions are covered in this section.

Type Of Construction
Verify the quality of the construction of your house. The building must be sturdy enough to support the ductwork’s weight and temperature.

The framework of older homes is made of lumber and nails. In contrast, lighter construction materials like plywood are used in recent dwellings. You should create a vent on the wall if your roof is made of lightweight materials.

For extra requirements, consult your neighborhood’s residential codes as well.

As a result of the requirement for more materials, such as the vent cap for sealing, horizontal vents are more expensive than vertical ones when it comes to venting a heater.

Consider the long-term effects even if you don’t have the money for the horizontal vent. In your area, the horizontal layout might be the most practical. Consider the advantages over the drawbacks.

Since the heating system might overheat, especially during the warmer months, there should be adequate room around the heater to allow air to circulate around it and the ductwork. If you don’t properly instal the vent, it will be simple for your house to catch fire.

Ventilate vertically if your space is small. However, if you have a vast space, you can vent horizontally.

Heat Source
Heaters can be vented either one way or both ways. You may vent Big Maxx heaters either horizontally or vertically. They have Category 1 vertical and Category 3 venting on their heater vents.

A test on heaters establishes the nett temperature and carbon monoxide concentration in the vent. The classifications adhere to the ANSI Z21.13 standard.

The most popular vent rating, Category 1, operates on a negative draught. Category 3 is currently working on a constructive draught. Even though these are technical phrases, being familiar with them can help you comprehend the vent recommendations.

Purchase the materials after determining the heater type and the permitted vent direction.

What Should Be Done To Vent A Big Max Heater?

There are venting kits for sale on the market. To ensure part compatibility, it is advisable to purchase the venting supplies at the same time as the heater. Additionally, it is simpler to select materials of the same sort and quality when you purchase them all at once.

The horizontal vent pipe can be as long as 10 feet. If it is longer than that, you should vent vertically.

No matter where the vent is located, you should purchase appropriate, high-quality venting materials. By doing this, you protect the security of your house and family. Additionally, try your best to find vent kits that are compatible with the Big Maxx heater model.

Refer to the heater model instructions as the type of vents affects the particular pipe thickness and material. Additionally, see whether there are any extra obligations to follow local codes.

Cost Of Installing A Vent

Making a decision also involves considering the vent’s installation costs because adding a vent is expensive.

Costs for adding a vertical vent to the roof range from $200 to $700. The price of labour might vary from $150 to $300 depending on the type of vent.

Installing a vent on a wall will raise the cost. The typical price for labour and supplies ranges from $1,016.70 to $1,230.90. The cost is influenced by the wall’s location, state, and finish.

Check to see whether work permits, taxes, and other fees are necessary before installing. These will increase your expenses as well.


A Big Maxx heater can be vented both horizontally and vertically. You must choose the vents’ position before continuing. The elements to take into account are the structure of the home, the available space, the type of heater, and the budget. Once you’ve made your choice, you may put in the vents.

With the exception of the vent site, the vertical and horizontal venting processes are similar. Horizontally through the wall and vertically through the roof are vents. Getting the correct measurements for the hole and ductwork connected to the heater is a necessary step in the procedure.

With the right vent installation, you may use your Big Maxx heater at home and benefit from it.
