• A. 10 x 10
• B. 10 x 12
• C. 12 x 12
• D. 11 x 11

Answer: (C)

The appropriate grate size for a water heater with 50,000 BTUs is determined by the need for proper ventilation and airflow to ensure safe and efficient operation. Generally, a water heater needs sufficient air intake to support combustion, and the size of the grate directly influences the volume of air that can flow to the unit. For a water heater with a rating of 50,000 BTUs, building codes typically dictate that there must be adequate openings to provide at least 1 square inch of vent area for every 1,000 BTUs. Therefore, a water heater with 50,000 BTUs would require at least 50 square inches of ventilation. The choice of a 12 x 12 grate provides an area of 144 square inches, which exceeds the minimum requirement and ensures that there is ample airflow to support the operation of the heater safely. This grate size also accommodates additional external factors, such as potential obstructions or variations in air temperature and pressure, which can affect combustion air supply.

The crucial role of proper ventilation in your water heater's efficiency can't be overstated. You know what? Choosing the right grate size for a water heater rated at 50,000 BTUs is more than just a technical specification—it's about ensuring safety and performance. So, let’s get into the nitty-gritty of this essential topic.

First off, you’ll want to remember that your water heater requires adequate airflow. Why’s that, you ask? Simple: a water heater with a BTU rating like this needs sufficient air to support combustion. Now, if you're scratching your head wondering just how much air it needs, here’s the scoop: building codes typically stipulate at least 1 square inch of vent area is necessary for every 1,000 BTUs. So, for your trusty 50,000 BTU unit, you’ll need a solid 50 square inches of ventilation space!

Now, it can be tempting to opt for a smaller grate, thinking you'll save space or cost. But trust me, that’s a no-go. Enter the 12 x 12 grate, which provides you with a whopping 144 square inches of ventilation space. Yes, you heard that right! That’s more than enough to keep the air circulating efficiently and safely, surpassing those code requirements with ease.

What’s more? This extra space isn’t just a nice cushion; it also prepares you for any unforeseen hiccups, like changes in air temperature or pressure. Picture this: if the atmosphere is acting up or you've got some potential obstructions lurking around, that ample airflow becomes a real hero. It’s not just about getting the numbers right—it’s about creating a safe environment where your water heater can operate as it should.

So, the answer to the question isn’t just a matter of picking a number; it’s about ensuring comprehensive safety and functionality. Check out your options, look for the 12 x 12 grate, and fill your space with confidence knowing you’ve made the right choice.

In conclusion, the vital takeaway here is that thoughtful planning for grille size can not only assist in maximizing your water heater’s efficiency but also give peace of mind. After all, when you install that water heater, you want it to work flawlessly without worrying about ventilation issues. Feeling empowered to make the right decision? You should be!
